- Today, I’m going to be removing my FiTech EFI and installing the all new Edelbrock Pro Flo 4 EFI system.
You can get the Edelbrock Pro-Flo 4 here: amzn.to/2yCkAyk
The Edelbrock Pro Flo 4 Electronic fuel injection system has a great installation guide that I encourage everyone who is installing this system to look through. But the step by step of the installation is:
00:00 - Installation Introduction
01:36 - Remove throttle body and intake manifold
01:46 - Clean heads for ProFlo 4
02:51 - Install the Wide Band O2 sensor
03:25 - Test fit the Intake, Throttle Body and all wiring and harnesses
04:31 - Put a bead of RTV on intake heads
04:38 - Install Pro Flo 4 intake and throttle body
04:48 - Tighten intake bolts to around 20ftlbs
04:53 - Install Distributor
06:28 - Wire up all the wires
07:42 - Spark Plug wires
07:48 - Air Cleaner Sensor
08:09 - Fuel Pressure regulator
Now if only it were really that easy, haha!

Very nice John, glad to see your enjoying the pro flo 4, took a long time for the video but I have to say it made my day can't wait to do mine, cheers brother.
Good luck with the 4
I've been running the pro Flo 3 on my 74 for the last 2 years and it's amazing.
Have my eye on it for the Storm Trooper. Thanks for the video, nice job!
I installed the Pro Flo 4 on my 1970 GTO Judge. Sequential port EFI is the game changer here. Throw all the throttle body systems and carburetors away and install this kit. Plus the software and tablet interface is far superior to the other companies at this price point. I have a 4 speed and the throttle response and mixture quality is perfect. Install new spark plugs and be amazed at how perfectly even they look after running with this system. My car can idle and cruise now at a much leaner mixture. Watch for the article in a future issue of Hot Rod magazine with my car.
Ive installed many kits at work, the FiTech are junk every one we've installed came back with injectors failing. The Sniper we've never had a single one come back and they run pretty good. For my truck how ever I am looking at this as if I did fuel injection swap I want sequential fuel injection.
Problem I keep running into is I have a C6 and ive yet to find a kit that offers a Ford Kickdown hook up to retain the kick down rod. Many talk about doing a cable conversion but that is just tacky in my eyes since youll need so much cable slack to ensure the kick down only engages fully at wide open throttle. The other problem I keep running into is no one at holley or edelbrock can tell me if a OE factory cruise control can pull the throttle open. I don't think vacuum operated cruise control will work on the sniper as those are quite stiff.
Not sure on the edelbrock, and I already have a performer intake, 1" phenolic spacer, and a 600cfm summit carb. Hate to spend $1300 on more parts if they wont work in the first place.
Nice video, and it was good to see you get it sorted out. I just got one of these for my ride, and read all the instructions carefully first (twice) and laid it all out on the floor to make sure everything was here and the connectors were working. I haven't installed it yet, but I see that a lot of the problems you had with initial install were addressed in the instructions (fuel pump, valve covers off when seating manifold, etc.) - I don't know if they have been added since your install, but advice for guys buying one of these, all EFI systems have lots of sensors and the setup is super important, so read up and play with it before you get down to the down and dirty install. I had to study up on some terms I didn't know and I'm doing youtube research now (hello!), and now I'm feeling pretty confident about the install. I used to install stuff before reading the instructions - sometimes was lucky and sometimes not. But this electronic stuff is not nuts and bolts, and if you have problems, tech support is going to ask you if you did this and that, and will send you to fix it and have you call them back after. As an old fart who has spent many hours scratching my head at problems I have created, I can say it's worth the extra time! Thanks for making this video, and to the folks that think it's a waste of money, just price a great 1000 cfm carb, a performance manifold, a digital ignition controller and a distributor and compare that to the Edelbrock kit, because you get all that, the whole system, in the box. I've found that off the shelf carbs are never perfect, and you have to have a dyno and a drawerful of jets to tune a carb to run as well as EFI. To each his own, but this kit ain't a waste of money!!! And it's made in USA!!!
Well said! Thanks man
I'm a Jeep guy, but I have great respect for an old school Bronco with some new school tech. Very nice!
Thank you!
Great vid, I like the problem thought process the best, that vacuum issue was surprising
Thanks man! Yeah it shocked me too
Glad you finally got it installed, loving mine. I yanked out all the fitech stuff and went with Edelbrock's sump pump, seems to work pretty good with the added benefit of the plug and play of it with the ecm.
Yeah I wish I would have gone with a Edelbrock pump
Are you running dual tanks? Mechanical pump to the sump which regulates pressure to the rails?
@@williamwright6157 just a single tank, the mechanical fuel pump supplies fuel to a sump and an electrical fuel pump inside brings the pressure up to 52 psi and then fills the fuel rails. This also prevents sending air to the injectors which can happen when fuel is sloshing around in the tank.
I really hope this is the fix I'm glad I waited before going fi tech if it lasts I'm on board with the purchase !!
Nice dude! Winning!
Thanks man!
I did the holley efi and it was alot cheaper than the eldelbrock system. I used the procomp 351w efi intake and fuel rails , aeromotive regulator , I bought the universal holley wiring kit , and holley efi throttle body . All said and done I had a little over 1800 in the system . I was able to reuse my msd distributor , I had to synchronize the distributor which was a pita . The best feature is all the upgrades and support with holley vs eldelbrock in my opinion.
Great video. Thx bro
THANK YOU SO MUCH. TOTALLY AWSOME VIDEO. TOTALLY AWSOME PRODUCT. TOTALLY AWSOME EFI INSTALL. THANKS FOR SHARING. I LEARNED SO MUCH.
Happy to help!
Good job I really enjoy your videos !
Thank you!
great video thank you
Ok, I'm sold.....
9:15 you only need the vacuum line for boost reference. Naturally Aspirated engines do not require the line nor the connection on the regulator. A PSI gauge mounted to the output helps make setting and checking easy and convenient.
Great video! Time to put on some miles
Yep! And they are fun miles
Is this the most anticipated Bronco video of the year??!?! I think yes hahaha
Hahaha! It took me too long to make it!
Very helpful doing mine now
Nice!
Yeah! I've been waiting for this video! Great job! Glad You got it running, surprised that you didn't see anything wrong with the intake gaskets to indicate a vacuum leak. is the dyno test next?
I put a bead of RTV along the back and no gasket. So that’s why I didn’t see anything. Dyno is next!!! Well, hopefully soon 😂
Just installed my Pro-Flo 4 on my 72 Bronco with a 351w. It has never ran better.
Yes 🙌🏼🙌🏼
Ben Cappon Hi Ben. What fuel pump are you using ? I currently have a Explore 5.0 swap and want to do a 351 swap. I’m running a intake pump
Tiko 433 I am running the Walbro GSL392 in line fuel pump. It was one of the few recommended by Edelbrock. The amp draw is low enough so I didn’t need to use a relay.
Was thinking about putting this in a 84 ran charger 360. I wheel off road all the time and my fuel is always at different angles.
I doing this install right now, could you post pictures of the wiring all buttoned up? Looking to see where and how you did your relay install.
I’m new to this so wanted to know if I could still use my stock truck gauges and also do I get rid of my stock engine harness and run the new one ?
I reckon there was a vacuum leak from the intake. Did that fix the headers glowing red problem?
Would I be able to run Edelbrock's fuel sump system with the pro flo4 or would it be best to run an EFI fuel tank and pump ?
Nice job working through the problems. Glad you got it figured out and running good. What is the price compared to FI Tech and Sniper?
It’s more expensive, but if you have to buy an intake and new distributor it comes out to pretty close
disculpa amigo, espero que me puedas responder mis preguntas las cuales son ¿como controla la inyección de combustible el sistema de edelbrock?, y ¿como es que dirige la inyección al cilindro que debe ir ya que no cuenta de sensores ckp y cmp?
Sounds like a lot of your issues came from trying to marry FiTech parts to the Edelbrock system. Those of us going with a virgin install would most likely avoid many of those issues. Totally digging the fuel rail system vs. the TBI. FiTech was always putting off getting their fuel rail setup on the market.
I am currently running an Edelbrock Performer Air Gap and Edelbrock 650 carburetor. The entire system will get pulled and replaced with a new fuel tank with an in tank fuel pump and new lines. I definitely see an Edelbrock ProFlo XT in my future.
Thanks for the videos, really helped making my decision.
Exactly! Yeah, for most people they won’t run into the issues I’m having.
Glad it helped!
I have a Holley in tank pump that I’m going to use with the Pro Flo 4. Pump directions say run a ground directly to the battery and the power line goes to the relay. But you had mentioned that the pro flo uses the negative side to switch on/off. This sounds like I could have the problem you did with the fitech unit not shutting off. Can you elaborate more on how you wired into the pro flo with the relay?
Great video! Bought the Edelbrock pro flo and will be installing soon. Question, you list the Edelbrock 3594 fuel pump which is advertised as a 10A pump, so I wouldn't need the relay you talk about, right? Thanks!!!!
Correct! I had to buy the relay because I was trying to re-use my FiTech fuel pump
So it was just the way you set your intake?
I was looking into installing this on my 66 bronco w/ a 302 but I have a couple of questions regarding the fuel pump and the distributor. I'm trying to decide if I should go with the edelbrock fuel sump/surge kit they offer or just get an in-line fuel pump and if so what in-line fuel pump would you recommend? Now I'm wondering if I would need their distributor because I currently have a gm hei distributor on mine. Any advice would be very helpful
John great video! I have watched all of your videos pretty much thus far. I am doing a complete frame off restore on my 69. Question about the fuel pump system etc.. Did you change this from what it was with the Fitech? Did you use the Fitech fuel pump kit and keep the same or did you replace certain parts? Edel Brock calls for 57gph min for fuel pump.. Thanks!
I kept the FiTech fuel pump. If I would do it again I would buy the Edelbrock pump that the kit recommends
That sure looks pretty.
It does
Do these come with a transmission control module?
You might want to check out the hood struts at Duff's. They're awesome
Oh yeah!
Great video I am waiting for my Pro Flo 4 comming soon! :) Was the fuel pressure a problem? Sensitive?
Thanks! No it ended up being a leak in the intake manifold gasket/RTV
Nashville Early Bronco Ok thanks! I noticed now you did not apply RTV around each intake port as the instructions describes.
Do you have contact information for to do a install
I went with the Edelbrock Pro Flow 4 on my 1969 Bronco with a stock motor. I'm experiencing hood clearance issues so I'm wondering what air cleaner you or any of your subscribers used. Thanks for the great videos. Chuck
Thanks Chuck! I pieced the air cleaner together. Parts from TBP and Autozone honestly
Chuck what did you end up figuring out for the air cleaner and clearance?
Did you have any problems with the kick down rod for the c4 transmission and did you have to modify anything to make it work?
I had to modify the throttle cable, pulled the old one out and went with lokar
So what was the problem?
You probably already know this and its after the fact but from what I've seen is you needed an open spacer under the FiTech or a notch in the divider on your intake to run the FiTech or units like it.
Hey Jon---did you end up using/needing the Edelbrock 8401 Kick Down plate? Getting ready to covert my 66 from FiTech to the PF4 and can't seem to find that plate in stock anywhere...
This is the one I ended up using: amzn.to/36lGzrX
Well done bro.... , i was wondering Can it be remaped the ecu of edelbrock is it possible ?
I don’t know if that is possible. Let me know if you find out
I think i will keep my carb!
Hi Jon---yanked the FITECH off my '66 and am in the middle of installing the Edelbrock PF4. I think I recall one of your videos about trying to use the Fitech fuel pump but it not working with your new set up. Which video was that? Thanks!
The fuel pressure regulator video maybe? I forget 😂
Which proflo system part number did you use? Were there any hood clearance issues? I have a bronco I'm looking at doing this to.
There’s a link to the unit in the video description 👍🏼 no clearance issues, but I do have a 1” body lift
Can you give us an update? Are you still running it and how is it doing?
Are you still running this system? If so how was this long term? My Sniper just gave up so I'm between this and the sniper 2.
It’s been great! I really haven’t touched in since I put it on.
Hey John,
How do you think the height of this pro flo is compared to your original intake with the fitech? Is your air breather closer or further from hitting the hood? or about the same?
It’s about 3/4 of an inch taller with the Edelbrock pro Flo
@@NashvilleEarlyBronco thanks for the reply. I appreciate the info.
Hey! I have just installed pf4 on my 289 Mustang. Mine says it runs lean 22.8 witch makes the computer (I think) pump in extra fuel. Every time I start it now it has waay too much unburnt fuel coming out of the exhaust. Did the O2 sensor test from edelbrock CZcams guide on O2 sensors and it works fine. I think I might have the same intake problem as you? I know it is hard for you to tell but I might suspect I did something wrong somewhere along the line
Check for vacuum leaks
@@NashvilleEarlyBronco I got it sorted. Even though O2 sensor "worked" it didn't work correct. Got a new one and raised the fuel pressure and now everything is perfect
Now that you have Installed both. What one would you choose?
Edelbrock. Every day. It’s way better
Did you have to splice into your wires to get your stock Gages to work?
It’s just the temp sensor gauge and for now I just have that running through the Edelbrock instead of my dash.
What ever did you do with that 4r70w you purchased a year ago? Did I miss something?
No, haven’t done anything with it except trip over it in my garage 😂
Well I hope you get to it before I do. Looking at controllers and efi that have trans control. Maddening.
@@NashvilleEarlyBronco should have used the holley efi system it can controll the 4r70w.
What is the link for your fitech edelbrock comparison video
It’s coming on Tuesday 👍🏼
Good Job brother, things don't always go as expected especially when using aftermarket systems. Way to stick with it, always remember the "ignition Tri-Angle"... Fuel, Air, ignition. A suggestion for anyone working on engines, a smoke machine. One of the first things I did on the stand after the ProFlow 4 install was smoke tested my intake for intake sealing issues. I just built a 400 SBF stroker going in an 83 Bronco. I decided to go with the Edlebrock Proflow 4. Engine went in to the bay yesterday and today will be getting the fuel system ready with new 10amp fuel pump, regulator and all 6AN routing. You are 3 years in to your install now, are you happy with the injection system? -- Mike
That’s a great idea!
Yep! I’ve loved having the ProFlo
I had to switch the fuel line also. How did you route the fuel line around the distributor?
I had to unattach on end and twist it, then reattach it
Okay thanks! Appreciate it.
Why did you remove the intake ?
The ProFlo comes with an intake built into it
And of course multisport efi will be better than tbi intake injection. Kind of a no brainer the edelbrock will have better drivability and throttle response etc.
So, since it’s been - what - 4 years 😳 Do you still like the Pro-Flo? What kind of gas mileage do you get? Any suggestions for someone (me) considering installing this in a ‘94 F250 351W ZF5 4x4? I’m hoping to get away from the ‘Bank’ style injector firing vs the Sequential Port FI that the Edelbrock system provides. Kewl video - Thanks!
Honestly still love the ProFlo. Drive it almost every day and haven’t had a single problem… well, not with the ProFlo 😂
@@NashvilleEarlyBronco what kind of gas mileage do you get? Is there a noticeable difference? Thanks!
@TJHill-qx9hy it was an improvement, but I’m still only around 10mpg
@@NashvilleEarlyBronco What transmission do you have? Are you running a C6 by chance so you don’t have Over Drive - correct?
You mentioned you had problems with the FiTech EFI, what were the actual problems you had that made you change it for another EFI system?
I made a separate video about it. The hand held controller went out and FiTech told me to send the unit back to be fixed.
I saw that video, was that the only issue? And was it simply a replacement for the hand held unit?
Biggest problem with fitech is the ecu is mounted to the throttle body. As you know computers and heat do not like each other. It's a cool for crusing car shows and what not but cross the country reliability just is not their.
Ah ok, Thanks. I suppose I will see what happens with my car then
You are right about heat issues, it would over heat on my 440 after shut down and not restart until it cool down. Bummer because I liked it.
Is this better than the fi-tech or holley efi?
In my opinion it is. It moves the ECU away from the heat in the throttle body giving a longer life to the unit
@@NashvilleEarlyBronco i wish i would of known about this unit before i did my rebuild on my k5 blazer..if you’re doing a complete rebuild with everything new this is the way to go..Since it comes with the manifold, distributor and efi system thats a bargain.
Exactly
What caused the lean?
Fresh air in the exhaust
♥️♥️♥️🙏🏽🙏🏽🙏🏽
Need a 20 ton press in my shop
Like your information in your videos. Please get ride of the "music" in the background. I usually leave your videos early because of it.
rookie here! why do you need a fuel pump regulator with a vacuum signal?
thanks inadvance!
larry
Hey Larry! The vacuum from the engine tells the regulator when to add in more fuel because of acceleration. Kind of like the cars that had vacuum running to the distributor for the same reason
I personally like the holley system better. I have the terminator tbi which uses a Holley HP ecu. Better firmware and laptop software. More tuneable, modular and upgradable. Aslo what i dont like about the pro flow is that it uses a single plane intake wich gives up a ton of low speed torque for a little high speed H.P. out at 7000 rpm. Not great for a street car or a truck.
Good insight! Yeah I’ve heard good things about the terminator
Running FiTech on 80psi?!
Those are nice but I would have to invest in a 6 speed transmission first. Without a good overdrive transmission the mpg benefits of EFI won’t really shine. I’ve never had a problem daily driving a carb engine or starting them. It’s the old 3 speed auto transmissions that drive me nuts! Lol
I’ve drove my old Chevy C10 in Nashville traffic many times. The carb was never the problem, it’s the screaming RPMs trying to run with modern traffic lol. Nashville is a nascar track lol 😂
Haha! I hear that. I have a 4R70w I’m about to install
Did you figure out if your header leak was causing your fintech to run rich?
It was a little bit yes
Haaaa he said angle socket thingy 😄
🤷♂️😂
Could do without the rock concert going on in the background. Don't need it, you and the install is what I want to concentrate on. Thanks, good video, sorry the music sucks though.
Thanks 👍🏼
OK, I am getting the edelbrock proflow 4
I have done a lot of research before I make the purchase, all the issues you mention, I already knew. I guess what I am saying before jumping into this do research on what parts are needed, and check if the parts are correct, and follow instructions to the T...this video is nearly useless, your basically saying I know nothing about this setup or what's expected.. it's like taking one step forward and 5 steps backwards.
17:20 why is there a ghost wiggling that wrench behind you?
Haha! Yes
Ha... I see it! That's nuts.
And it never stop moving
Make a video of the good stuff you cut out. I'm a patient human.
Why not a HEI distributor, eliminates the coil placement.
The distributor came with the system
Nashville Early Bronco I put the Fitch on my 302 f100, I ran the retro in tank pump for fuel, 58psi. 3k miles no issues and thank you for the videos. Now I want to run this pro flow 4 on my Pontiac 455 ci. 7.5L.
Pretty sure you don’t run vacuum to the regulator. That’s for boosted applications. Remove that.
No thanks, I’ll stick with carbs. For that money, you could of added a B&M blower.
They dont make blowers for 302s..
I'm using a Holly 600 carburetor on my 68 Bronco 289 engine, runs perfect $330 That's the deal
Don't be fooled none of these efi setups are not really that easy, if he's got a Blaster II coil it can overheat if not straight up.
Why would you remove the distributor unless the kit comes with new, it's a Ford lmao
Why remove the distributor? Because it’s impossible to replace the intake manifold with it on. Lmao
FiTech Sucks!
fastjp72 I’ve been happy with my fitech! TBH I think most fitech issues are not related to the unit. Most seem to be install or other u related issues
@@bpdispatch6433 Not true have seen many problems with FiTech and there quality. Cheap chinese made compared to Edelbrock USA & Holley USA+Canada.
Agreed! Great video.
i know 3 or 4 guys running fitech and have almost no issues i was thinking of getting a 2bbl for my 318 poly . i have herd of lots of issues with edelbrock heads so go figure
Acer tablet, now that's some high quality shit. NOT
