Recently my uncles lml had a Cp4 fail at 130k. I know he doesn’t maintain his trucks very well, meanwhile my dads lml is still going strong at 180k but his truck has an air dog lift pump along with aux cat water fuel separator’s. We’ve been weighing heavily on weather to go with the Cp4 system saver or do the cp3 conversion and we ended up going with the cp3 conversion. Our reasoning being that i couldn’t find anyone who had installed one of these savers, had their cp4 fail, and it saved their injectors and fuel system. Not to say it doesn’t work I just couldn’t find any evidence to prove it first hand. Secondly it’s worth the extra expense to take the time to do it when it’s convenient rather than have it leave us stranded when it’s inconvenient. Third it’s just worth that piece of mind to know its not going to be an issue. It will be interesting to take the old Cp4 apart tho and see what kind of condition it’s in, and if all the initial measures of installing the extra filtration, water fuel separation, fuel air separation, and positive fuel make a difference. I might take it apart and find shavings showing it was on its way out or it may show no evidence of failure. I’ll find out this weekend.
Any updates on it ?
I’d like to know how it looked as well
Ok guys I had my cp4 fail on my lml with 105k on it thank to the system saver I put the updated cp4 and back in action also put a new system saver for piece of mind
Gator Amador did it prevent debris down stream from the pump?
@@josephthomas9735 yes it did I installed a new updated cp4 pump and system saver and back on the road no sensor problems or injectors
@@josephthomas9735 the pump was a good task to replace took a good amount of time but system saver was definitely worth it it both my buddy 10k due to cp4 falure with no system saver
Gator glad to hear it just put one on mine
@Dan S Lincoln Diesel Specialties
I will definitely add this to my truck along with a lift pump once it goes out of warranty
Let’s be real, even after the CP4 shits the bed, and assuming you have this installed. The mechanic is still gonna condemn the fuel rails/entire system. It’s his name on the repair.
i guess the big question is " how large of particles can the injectors safely ingest"? if they can manage 25 micron and smaller this would do the trick.
If the CP4 goes out after installing this Exergy Metering Valve, How can you be sure that No Metal Shavings passed through the Exergy Metering Valve? Is there other place to look for to be sure?
Have you had any feed back on the system saver yet
Hey guys, is there a video out there that shows how to install the exergy inlet metering valve? If not would you do one or let me know where to get instructions on how to install it?
Rody Johanna Hale any update on this?
I would also like to know.
Watch "Exergy fuel system saver Duramax" on CZcams
czcams.com/video/BPT3J41nHZQ/video.html
Show me that it works and you can take my money .....
yea Agree. can that screen hold back 25-30k lbs of fuel pressure. I am not thinking it will but great IDEA...... would be smart that to have a valve that once it senses plug up the high pressure valve goes off and lets the fuel out to a canister or something. that collects the fuel and shavings.
@@Mikefngarage well we know the stock inlet definitely can’t lol
@@Mikefngarage
Is there any way possible to have an extremely fine micron filter after the pump and before the fuel enters the fuel rail ??
I have one installed on my 2015 LML but haven’t heard of any actual cases where it saved downstream equipment, injectors, lines etc???
Thanks for the info...ill be doing this to my 12 lml.
did u do it?
How can you tell if the injentors were not damaged or contaminated after the CP4 breaks down and you have this Exergy?
Thanks
Here at the shop we send all injectors out to be tested when there has been a confirmed injection pump failure and recommend that as the best way to be sure that they are clear of contamination. If you have a set that you would like to have tested, please give our team a call at 630-277-8239 or email us at sales@wcfab.com and we can help set that up for you.
Will this work for the Ecodiesel CP4 pump as well?
Is a loong crank on my 2013 LML before it starts a sign of my CP4 about to fail?
Wouldn’t it be beneficial if someone made a filter to install on the high pressure lines going to the injectors?
Or am I seeing what basically is a filter on the high pressure side ?
Do you recommend a lift pump as preventative measures also?
All stock, 2013 LML I have no intentions of tuning or mods.
This screen will filter out contaminates just before the fuel is pumped into the high pressure system. Yes a lift pump is always a good investment.
I installed mine, install was easy, my truck started like normal after install and then died within seconds and only cranks now. I purged fuel line to make sure air was out and it still only cranks. My truck ran awesome before I touched it. I just order stock OEM regulator to swap back in and hopefully it will start and run awesome again, at this point I wish I never touched it, it somehow turned into a nightmare and not sure what's going on.
So its started no problem with stock FPR, not sure what the hell was wrong with the system saver they sent me, but it only caused extra stress on my truck besides myself the last few days, what a joke. They should reimburse me a lot more then the $250 for this BS. I guess Ill end up doing CP3 sooner then later, but truck runs awesome again thank god.
Dang.... so what's the update here?
To you loosen shrapnel and send it through?
I have a 2016 lml with 252000km on it. I've noticed it surging lately, but only while I'm in gear and truck is stopped. Could this be a sign the cp4 is weakening ?
Yes
Is this a part that can be self installed? Do you need a dealers computer to install?
So in your opinion... considering the cost (roughly 3k) and lack of emission intact CP3 conversion kits, should we assume this is really the only protection/solution we have (in addition to running a lift pump and lubrication additives) on a emissions intact LML?
You are correct Scott!
I believe their is emissions intact cp3 conversion kits, i think fleece offers one
I have the System Saver installed on my 2012 LML, now with 172,000 miles on the factory CP4 pump. I installed it because it was a cost effective alternative to a 50 state legal, no tuning required CP3 conversion. I'll get all the miles I can out of my original pump, and as long as the System Saver does it's job I'll have the option to replace the pump with either another CP4, or go with the CP3 conversion. I'm not running a lift pump, but I do use a lubricity enhancer at every fill-up.
Updating my previous post, I'm now at 198,000 miles and running strong. I did install an AirDog II 4G system and fuel tank sump this summer.
I am interested in information on the system saver you are using?
I bought this exergy saver brought it to a garage he couldn't start it after installing it , evidently he spoke with exergy and got it started, I paid him now my truck is not running right like it starving for fuel please help and keep saying to replace fuel filter and I did. This truck will not go fast at all no power. Mechanic convinced me it need a new pump si I ordered a cp3 conversion carb compliant pump and hoping this is the problem and I'm not just throwing parts at this. If anyone has information please give a helping hand thanks
What did they do to get it started initially ? I installed my Exergy regulator and it wouldn't start, installed my old one back in and still won't start. Truck was running perfectly before install.
Will this work on a Jeep Grand Cherokee Diesel 2018?
We have not confirmed compatibility of this product with the EcoDiesel engines at this time.
So there is still a chance of contamination getting in if it doesn’t cut the engine fast enough
Correct. To be clear, this part is an MPROP with a upgraded 25 micron filter screen design which offers significantly finer filtration levels than the stock 80 micron unit. The Exergy product also resists the delimitation or tearing common to the stock MPROP design which can allow significantly larger and more damaging metal debris into the fuel rails and injectors. This reduces the possibility of significant debris from reaching the injectors in the event of a CP4 pump failure. The only guaranteed way to prevent CP4 failure is to remove and replace that pump with a more reliable CP3.
@@WCFab exactly what I was thinking just gonna change it right out when the truck gets here thank you
Will this work on a VW CP4?
yea that was my question too. I am doing a cp3 mod right now. Honestly it is not hard to do compared to the duramax. But super expensive.
Great idea. Will this work on my 2015 ford f350 with that same cp4 fuel pump? Also what would be the cost of a upgraded fuel pump? Thanks
Hi Steven, we have a model which is compatible with the Power Stroke CP4's as well. Please give us a call at 630-277-8239 to speak with a member of our team and we would be happy to help you find and price the parts specific to your application.

Come in GM 80 micron? Geez might as well use a screen window
This thing doesn't do anything. I'm currently replacing an entire fuel system that had one installed.
Thanks for the video Jason. Do you have any pics of a failure with this installed?
We do not have any reports back yet of a pump failure with this regulator installed, over time I am sure this will come about.
Wehrli Custom Fab Hi, I just wanted to touch base with you again on this . Do you have any reports yet of failure with this valve installed, and the outcome ??
Thank you
WCFab, have you had any reports over the last year of a cp4 failing with the SS installed? Did it do what it was supposed to do?
@@rjtonka1781 I had my cp4 fail in my 2015 lml with system saver installed and it saved the injectors and sensors put the updated cp4 and new system saver back on the road again
@@gatoramador1847 Glad you were able yo save your system. Do you remember how many miles your truck had when the pump failed?
Is there a video on installing this? I plan on purchasing after 100k Factory warranty goes out....
we do not have any install videos however it is pretty straight forward, maybe 2hrs at most.
I'm currently doing this and will be posting a video on it. Pretty easy though just get yourself a long T-25 torx bit that's only special you really need. Move A/C compressor out of the way move couple of wires and it's fairly easy.

Nice
Do you recommend if I have cp3 pump ?
No sir - a CP3 Pump is not necessary for this device. In fact, it's designed to work with a stock fuel system and help avoid problems associated with CP4
Thank you
Is this lift pump friendly?
Absolutely. The majority of these that we install are being fed by a Fass Lift Pump.
Yes, have the Fass on mine as well.

I purchase this.Dealer told me 12.8 hours of labor to install.Is that correct?
Something there doesn't sound right and sounds like there may be some miscommunication happening. We typically bill 3 hours of labor for a fuel system saver installation at our shop.
@@WCFab that's what I told him.they called it a Fuel Pressure Regulator.Replacement.Is this metering valve, the fuel pressure regulator?

Will a 25 micron filter stop *all* metal particles from getting into the injectors after the CP4 fails? Seems like this is more of a half-measure, rather than addressing the real issues: no lift pump and poor design of the CP4.
Well fuckin duh..
Seems to me you got a couple options. Sell the truck because of the poor design. Keep the truck roll the dice that you might have to spend $8,000 on a whole new fuel system. Replace the cp4 with a CP3 for thousands and thousands of dollars period or use a low cost part that will potentially save your fuel system and a lot of your money. It's a no-brainer
@@chevydmax1000 Right, use a band-aid that may or may not work instead of spending a few grand on fixing it right. Dude, if spending a few grand makes you weak in the knees, you need to get out of a diesel immediately before you have a stroke. That's a no-brainer.
Good thing it's America you have your opinion I have mine. If you want to waste your money go ahead I'd rather use it for other things and use the low-cost part to solve a bad design. It's already been proven to work many times by many people. And that's a no-brainer. Have a nice day
@@chevydmax1000 I have a 2014 6.7 Cummins so this isn't a problem for me. But if it was, I'd fix it the right way and not use some half measure. Why do you think Ram went back to the CP3 and not just put one of these in there and save a bunch of money? Yeah. Anyways have fun with that.

Has this issue been rectified on the l5p, if not does exergy make a metering valve for a l5p
L5P has a DENSO fuel injection system, no more Bosch.
👍🏻
If your deep enough in the motor to get to the top of the cp4 just change it with the new version. This makes no sense to me
To get the the metering valve you just have to unbolt the alternator I have done several for them. Very easy and simple instal.
I do not recommend unless you want your truck to no longer start after vigorous ways to get it to start again, installed now cranking and no start. Even priming won’t help, my truck ran amazing before just wanted to do a little upgrade.. WARNING do not do this.
Any updates my truck won't start after the exergy install just cranks I reinstall the oem sensor and still the same issue
@@sahuayo1995 so I had ti get the air pumped out after installing to much air got into the truck so the mechanic had to bring this special machine that pumps out the air and I was able to get it going again
@@lucianalderete9008 What was the machine called that they used to pump the air out, and where does it hook up ? Did you end up buying a new oem regulator or were you able to use your old oem regulator?
I'm having the exact same issue as you did. That Exergy part has bricked my truck for the last 3 weeks, wife is not impressed.
I love how your marketing this product as a product that will save your cp4, you clearly stated in writing on your thing that this MROP will prevent catastrophic cp4 failure and that's false, this will not save your cp4, maybe do your false advertising someplace else. People this only saves the rest of your fuel system in case of failure.
Hi Cole, thanks for commenting on our video to help make us aware that our current cover text does not represent our intention with this video. We'll reconsider the wording used there to help make that more clear in the future. As you say, and as Jason also confirms in this video, Exergy Performance did not design this part to prevent the CP4 pump from failing. IT DOES NOT DO THAT. What it does is provide a dramatic improvement to the MPROP filtration so as to significantly reduce the potential for failed pump debris to contaminate and ultimately cause catastrophic failure to the rest of the fuel system / injectors downstream of the CP4 pump. It is the contamination of the injectors, rails and return lines into the fuel tank which makes CP4 recovery repairs so expensive, not the actual cost of the pump itself. To be absolutely clear, in our opinion, the only guaranteed way to prevent CP4 pump failure in these trucks is to completely remove it from the engine and replace it with a more reliable CP3.
Do we know of anyone having pump failure with this system saver on?
martin Pulido so it won’t prevent failure. It will save your injectors.
Wehrli Custom Fab I know it won’t save the pump from going, but is there any guarantee it will 100% keep debris from passing it?
I would pass that question on to Exergy - it's their part. We're satisfied with Exergy's testing to put this on our LML.
Wehrli Custom Fab awesome thank you
Wehrli Custom Fab I have contacted Exergy about this and they never replied
Why wont you guys release confirmed saves,seems like in every duramax forum exergy and vendors dance around the topic.I have 1 in a box on my bench but till I see proof that's where it will stay.
Exergy has tested several complete fuel systems after CP4 failures where the system saver was being used and the rest of the system did not show any signs of debris that would cause any damage. I'm sure a day will come with the thousands that are in use where debris to some degree gets thru, but for the cost and the piece of mind this part will give you MUCH higher chances of saving your fuel system verses the OEM part. Remember its still a screen that FLOWS fuel, but any debris that COULD potentially pass thru would be so small that it wouldn't have any measurable negative effects on the components down the line for the short term that the components would still be operating for, before the engine shuts down.
They don't care if it stays there forever. You already paid them for it.
@@aaronj08ar luckily I was able to sell it for what I paid.
You must have plenty of money to pay to have the whole fuel system replaced. Something that can save catastrophic failure for not too much money is a no-brainer in my book. It makes perfect sense that it would work like a charm
@@chevydmax1000 except it doesn't save shit,CP3 conversion took care of it no problem, thanks for playing.

I call the company I order mine already they say will fit
Don't waste your time with this thing, super cheap made in china junk. Just 3 weeks in and got a P0089 code and took it out to find the molded metal part around the screen was already coming apart (guessing because of the high pressure, not made for that) so would do you no good even if they just sold you the screen. Soon as i put the OE sensor back in, no more code. I bought another one a year later and not even trying you can destroy the rings that holds the screen with the lightest touch. Absolute junk, i haven't tried any of the disaster prevention kits yet, i've just been always using additives like extreme lubricity, better than worrying about the screen parts coming apart. If they were using the OE part (BOSCH 1462C00998, made in Germany part) and made the metal parts holding the screen better that could hold the pressure, i could see this working, but they're just using cheap china junk and charging 3 times what you can buy the Bosch part for xD, this is honestly beyond embarrassing.

2 confirmed case's that the system saver failed done by a un biased 3rd party shop,which is what I was waiting on,of course wehrli wont say they failed.240 dollar paper weight.cp3 conversion is the only remedy.
justin hess, have some links to these confirmed/tested cases? We haven’t seen any. We have seen several failed systems and the injectors were tested clear and reinstalled.
@@WCFab local shop here in Maine,don't wanna name shop but shavings found throughout the system,also another 1 was a Chevrolet dealership in Idaho.shavings in tank lines and injectors.Those cases coupled with whats happening in the forums I am all set man.I am gonna stick to optilube good fuel,fuel filters evey 10,000.And when I hit 1000000 cp3 conversion and when I hit 120000 and emissions go out of warranty I trading for a 2500 gasser,fuck the EPA and fuck modern diesels.Im not against them hell ill probably run there kit and cp3,but the system saver was hype and they made a ton on "peice of mind".I fell for it,after reading about surging idle,no starts glad its still on the bench and not in my rig.
