Thanks for taking the time to get good camera shots and explaining-this was very helpful.
Finally a good vid on this thanx brother 🙏 saved my burban
I found the vac tube cracked on mine. it was rather challenging to get it right. but the reg itself was fine. Vac leaks are massive on these systems.
Shop just quoted 2.5 hours labor for fuel pressure regulator on my 7.4 and now I see why 😮
Good job keep up the good work.
Weak fuel pumps can create a lean condition, same engine swapped in two different Nissan 240sx proved this with my issue. Hard starts with one, no issue with the other.
Certainly can, the fuel pressure gauge will tell you that story for sure. Critical tool for this kind of situation.
Great video
Thanks for the video bro
I dont know if you will see this but i could really use some help . I got a 99 chevy 3500 hd. 454. I replaced the fuel pump .the regulator .an it still peters out when i am trying to give it gas in gear. I replaced the filter to it has some really nast stuff in it. When i had the manifold off i cycled the key an all the injectors were workin i dont know how much they each should spray out tho. I i do know its around 45 to 48 psi and when i rev it after its warn it drops below 40 as im hitting the gas is it supposed to go up when i rev.
Great video thank you
Thanks for that.
Thank you for this, going to go at my truck in a day or two. New injectors and regulator. How did the fuel rail disconnect from the regulator?
Great video, you think the ACDelco item you used would work on a 545 Crusader Boat ?
If it's the same engine then yes, I don't have a clue what they have in the boat though lolol. Ours is just a regular ole GM 350 and its no different than what you'd find in a vehicle other that the cooling.
Does this problem explain random power loss that goes away on its own if u give it a minute off the gas
It could, I'd rent a pressure guage from the auto parts store or grab a cheap and check the pressures over time. That's the best way too know for certain
Did you use both clips that came with the fuel pressure regulator?
Oh man, it was sometime ago and my memory isn't the best. I'm pretty sure only the snap ring is used on this engine. If you pay attention removing yours it should be very evident.
What parts did you order from Amazon please
They're in the description of the video. I'm currently driving to Louisiana, so if they're not working let me know and when I stop ill.update them.
How do I hook up the gauge?
The Schrader valve right behind the upper coolant hose coming out from under the intake. Should have a black cap on it
Oriellys price matches amazon
How much to fix my truck?
How much for the parts, or how much for me to actually do the job? lololol

I mean, it would be far cheaper to pay someone in your area honestly. It's not a difficult engine to work on at all
