How to change the Fuel Pressure Regulator, Silverado, Sierra, 4.8, 5.3, 6.0

[@boomcity4942]

Simple task. Straightforward instructions. Thank you!

[@DivineSpeed]

Thank you. I hope it helped. Thanks for watching.

[@SRahimAdams]

Question - I just obtained my new one from ACDelco, has 3 o-rings. When you pulled out the old one, I saw the blue ring still attached, but I also have a black one of the same size and the smaller one. Thanks!

[@albarqi122222]

bro i just pulled mine put and it only has the blue and black one without the smallest one and i won’t replace the regulator and i’m worried there the small one lost when i pulled out the regulator is it has two or three o rings

[@albarqi122222]

please answer because i worried if i put regulator back with two o rings will leak fuel later thanks

Will this make my truck not start. I replace fuel pump and filter already won't start I think it cranks

[@DivineSpeed]

Yes, if the regulator is not holding pressure, the engine will not start. Best way to check is with a fuel pressure gauge.

[@67akhunter]

Do you think it could have been the split vacuum connection? It looks bad.

[@DivineSpeed]

Cliff Sommerville oh possibly but this regulator was actually bypassed because I was using a boost reference regulator. I had decided to use this intake on another engine and had to change regulators because I had purposely destroyed the original to allow fuel to pass through it. So there's a bit of a back story with that intake and regulator. It's been around.

[@fernandezone-1396]

I like to know where is that located 🤷🏾

[@DivineSpeed]

Drivers side fuel rail under the plastic cover on the intake.

[@Disrupter37111]

Whats the difference between the vacuum tube being on the side like yours and the ones with it on the top of the regulator? Mine has the tube on top but my vacuum line doesn't stay on due to it having that orientation. If theres no difference then i will gladly order one with the tube on the side as its much easier to work with cheap parts but id like to get it right the first time.

[@DivineSpeed]

As far as I know, there's no difference. The only key thing to worry about would be making sure it makes the correct pressure.

[@coreyneedtoknow3959]

There is a difference the one with the hose out the side, as it sits...is a smaller dia tip-short pipe...the one with the tip-short pipe sticking up the top, as it sits...has a larger diameter by like 2mm...and sadly costs more...leave it to GM-Chevy to have this horseshit design :(. My just screwed me...

Enrique Vizueth I would assume the top left side of the engine attached to the fuel rail if it is a V8 gas engine. However, I've never worked on a van engine and I can't say for sure.

@@stanza77 okay I was just doing some reading and it is located on top of the fuel pump. Based on the pictures, It is on top of the fuel pump hat, but can be replaced without removing the fuel pump.

[@jaythomas3224]

Im getting conflicting reports some mechanics say its part of the fuel pump assembly in the fuel tank. Advanced auto parts online says may not fit and it looks like that one.

[@22kpar1xcyberdyne9]

Never trust the people who work at auto part stores. They are basically the same retarded people who work at McDonalds. No training and no mechanical knowledge, so if a part isnt in their computer system they truly believe that the part does not exist. Lastly a fuel pump does not have a regulator in the tank. It must rely upon engine vacuum to work and there are no vacuum lines running to any fuel tank.

[@coyote311]

Some of them are in the fuel pump assembly and some are on the fuel rail line. Pretty simple to check and see if you have a vacuum hose that goes to it on the rail. If you do not see this in plain view on the rail then odds are its in the pump and you have to take the pump out to get to it.

[@DivineSpeed]

Silverado and Sierra has the regulator on the fuel rail. Ford put a lot of regulators in the fuel tanks.

[@coodapop1535]

The one at the tank is a fuel pressure sensor as far as I know , my 02 4.8 has the regulator at drivers side fuel rail

[@mattpipke5716]

So, Question, I need that rubber part that goes on the pressure regulator, where can I buy that? I am not finding them online, maybe a junk yard or a dealer? Mine seems clogged, it looks like it leaked, and then got sealed temporarily but it also clogged it, so I think this is my culprit not the regulator. I know this is an old video, but I hope you see this, maybe can guide me to where I can find the part I need.

[@DivineSpeed]

Matt I know exactly what you're talking about but unfortunately I do not know where to buy a new one. if nothing else, try to use a rubber vacuum line. It may not be the right part but at least you will be able to diagnose the issue.

[@patrickmirek1041]

@Matt Pipke you can buy them on Amazon it’s called a fuel pressure regulator vacuum tube. Hope this helps

[@GweGwe-lu9ob]

2002 Chevy Silverado check engine light came on and got it checked and said it’s a misfire and it said that this is most likely the problem with it but I don’t know if this can cause a misfire

[@DivineSpeed]

I can see it causing a misfire if the fuel pressure is low while the engine is running. It really needs the designed base pressure of 58 psi. It would be like it is running out of gas.

[@derrickvennie3062]

Great vid I have a 01 Silverado 1500 4.8 it has new plugs and wires new knock sensors new o2 sensors a new engine coil new fuel pump and filter but I am still getting a p0171 and p0174 code too lean in banks 1 and 2 do you have any clue what could be causing it to run to lean and i also installed a new maf I’m stumped sprayed carb cleaner around found no leaks plus a new egr valve

[@DivineSpeed]

I'm sure you've already checked it and replaced it but I would double check fuel pressure. Seems odd that it's in both banks. The first thing that comes to mind is fuel pressure regulator.

[@derrickvennie3062]

Divine Speed Team put a new one on it runs good now but I still get random misfires

[@jamesmartinez1633]

@@derrickvennie3062 Did you ever figure out the problem? Was it a bad distributor cap?

[@trev1481]

Should have been Intake Manifold Gasket leak (or a cracked plastic Intake manifold). Spraying carb cleaner does not always find leak, especially if its on bottom side. There is a TSB about this along with one on the FPR.

[@paullambert7110]

Did u ever figure it out currently having same issue and I replaced everything

No they are not adjustable. But yea they look like they could have been.

I'm not 100% sure but you have a returnless fuel system and I believe the regulator is on the fuel pump assembly in the tank.

That's a good question. Make sure part of the old regulator isn't still stuck in the fuel rail. I think I've had that happen before.

Why did you replace the fuel pressure regulator? Were you getting a lean codes on the check engine lite? Also I see a rubber fuel hose with clamp in the video. Did you replace both feed and return hoses with rubber and remove all the metal ones going back to the gas tank? Thanks

[@DivineSpeed]

This was actually on my racecar. I had gutted the factory fuel pressure regulator so that it would bypass the factory piece and go straight to an aftermarket regulator. However, typically they start to fail when you have to cycle the key a couple of times to get fuel pressure built up before you start it. They like to bleed off the fuel making it harder to start.

[@kcid66]

@@DivineSpeed Ok Thank You .The rubber fuel line I see, that is just regular neoprene fuel hose and that will hold the higher fuel injection pressure that the vehicle puts out?

[@DivineSpeed]

@@kcid66 yes it was the higher rated pressure line but I was always worried about it slipping off of the fuel rail. The fuel lines have all been changed over to AN lines now.

[@04DynaGlyde]

Where is it located?

[@DivineSpeed]

Drivers side of the intake manifold on the fuel rail. You will need to remove the engine cover to see it.

[@luisquintana1056]

I have a 2008 Chevy silverado has high fuel presure any ideas the fuel pump has been replaced twice 😫😫😫😫😫😫

[@DivineSpeed]

High fuel pressure? I'd say that would be a regulator issue but I haven't worked on one that new. I'm not sure where the regulator is located on a 2008. It might be part of the fuel filter. If so, that's an easy swap.

[@snajvar84]

Haha I just needed to know for sure where this thing was located. My is throwing a code and fuel econ has dropped (not that It was that great anyway lol) but I don't wanna get straned an 1hr from home when I'm at work 😅

Should be on the drivers side under the plastic engine cover. I hope that helps. Thanks for watching.

Yes. Should be exactly the same.

[@yojo5873]

How did you know it was bad

Fuel would bleed off after parking the vehicle and I would have to cycle the key a couple of times to build fuel pressure before it would start.
