- Learn how to replace your fuel pressure regulator in your Chevy Lumina the correct way. Your regulator takes vacuum from the intake manifold and allows fuel to be pressurized in your fuel rail for optimal fuel delivery to your injectors and then eventually into your piston chambers.

I did make a mistake in the process. I did not remove all the fuel from the fuel rail (it was pressurized). You need to go behind the power steering pump and drain the fuel into a cup (WATCH OUT because it will shoot out since its pressurized). In the video I simply take the footage from the ending and put it in the middle to show you the schrader valve that you need to depressurize. I hope this is not confusing. Anyways... enjoy the video...

For anyone wondering and stuck with this job like I was. The wrench size is 15/16.
Thanks for sharing your experience. I used this video to confirm my Buick skylark fuel pressure regulator failure and learn how to replace it.
It answered all the questions I had. Good job!
This video was so helpful! I wish I would have looked it up yesterday. I couldn't figure out how to separate the fuel line from the regulator but. To unfasten the screw, I used just the star bit and a 1/4 inch wrench which was also frustrating when I dropped the bit a couple times. Thank you for making this video, now I'm actually going to get it changed instead of just practicing how to detach and refasten.
Thank you so much, Sir! I don't like second-guessing myself but I was doing this for my mom's vehicle. It just actually took a bunch of WD-40. I'm just glad that I got all of the pressure out of the tubes before I had to take out and chose to just clean the throttle body. This is probably one of the best how to on TH-cam!
Joel Klimkowski thank you sir! Comments like these really help me keep posting how to videos
Excellent video, Thanks so much!
01 Cavalier is identical but bracket on the other side. Thank you for your video it helped me a lot.
I did this on my 2004 Buick Century in about 15 minutes. Well the second time after installing a bad regulator (grr). I didn’t remove the throttle body but merely stuck open the cruise control with a screw driver to get burnout if the way and backed off the outer throttle body bolt. Took me awhile to learn all that.
Thank you for your video, it made everything more easier. Thanks Bud.
Thanks for the tutorials. This is very much helpful 💯💯💯💯💯
Gracias por tu valioso aporte a la humanidad. Dios lo bendiga.
Thank you very much. You have a great demeanor and easy to follow information.
thank you. Im glad I am a help to people who need to replace this
Thanks man!
so to prevent your fuel spillage you can pull the fuel pump relay and then start the car it will empty the rail and then stall out due to lack of fuel in the rail then once you are done replacing the regulator just key cycle the ignition a couple times without starting the engine to re pressurize your fuel rail
+Stephan Bertram oh nice tip 👍
Is it bad if fuel leaks or no will it mess with the pressure?
Great idea
Note working on fuel systems may be a good job for a professional. Always wear safety glasses. What works for me is this: Vehicle must be fully cold. Have a fire extinguisher close by. Safety first. Start vehicle, let run for say 30 seconds, then pull fuel pump relay/fuse. Let vehicle stall, turn off ignition and remove key. Let vehicle cool. Put paper towels around any fuel lines that may leak fuel.
I do this for any fuel line work, including fuel filter. Spraying fuel on a hot exhaust component is very dangerous. I have used the process of pulling fuel relay for Audis, Volvo, Oldsmobile, and Dodge Neon.
One time a I had misfire CEL come up from vehicle stalling, I cleared code and it did not come back.
If the regulator is leaking, the system will depressurize at some time. Not sure if that is after say 12 hours or 3 days? And is there pressure on the non leaking side? No idea. Best to pull relay/fuse.
Here's a trick I found; Notice that there's a hole in the bracket where the TV/throttle/cruise control cables enter? You can feed a long socket extension or long 1/4" bit extension through this hole and not have to remove a damn thing other than moving the PCV and vacuum tube to the side. I zip tied the throttle wide open to have clearance for a socket and extension.
Thanks for the help
You make replace and fixing easy , I enjoyed your video , I already subscribe and definitely liked it , I'll definitely check out the other videos as well , laters ✌🏼
Hey thanks man! Got loads more fixes and stuff coming.👍
Good video
Do you know where the fuel pressure regulator is on 2013 Impala LTZ 3600? Thanks and very smooth video.
What is the thing called that is on the upper intake manifold it's a little square and the hose runs to the fuel pressure regulator?
Thanks for your video.
Did you have a no start issues for why you replaced the regulator.
My Buick Rendevou is having a no start issues. New pump and pressure sensor.
Our 2004 Montana same problem-no start up. The fuel regulator was stuck closed. New fuel filter but not new fuel pump and it's good to go
Doesn’t seem too hard. Gonna do this on a 1986 Bronco soon. Hopefully it all works out
You said the bottom pliers counter clockwise but in the video you went clockwise?
Saw that too✌️
Easier if you just pull the fuel pump relay and let it run out of gas. Also noticed you didnt use vaseline on the o-ring during reassembly.
Gracias
+Orlando Novoa de nada
all you needed was a swivel to go on the socket
Is there an o ring on the bottom of the regulator or just where it goes in to the fuel rail?
Yes I believe there is. Use a pick to get them out
what is the size of pipe's nut please.
What is the line you moved out of the way of the fuel pressure regulator?
Chris Goodyear PCV (Positive Crankcase Ventilation) Hose
Where does that plastic line next to the regulator go I can freaking find where it connects
the first line he removes I cant find the far side end of that plastic piece.
Do you have to undo the battery first for this type of work?
Thank you it was very helpful
I can't seem to get the flexible line and steel line to move forward at all.
Are you referring to the EVAP connection? Or PCV connection
@@AutOdometer the gas line that runs to the bottom of the pressure regulator. On most of these engines, there is slack to pull it away from the throttle body but I'm not able to on this 3400
Will this also work on a 2002 Grand Prix?
Brady Dempsey it will work if its a 3100 or 3400 sfi
tyler alright, thanks man.
Next time Show how to repair the fuel rail pressure regulator for 4p10 engine
I’m working on a 3400 and the fuel line isn’t expandable like ur 3100 shows
Seemed easy, but I don't want fuel in the face or everywhere else. Don't know if I could tackle this or not.
I feel confident to do this myself!
Like!
Nex time pull the fuel pump relay start the car couple times the engine should suck what ever fuels left in the lines once engine won’t start anymore the lines should be clear
Or maybe just pull the fuse to the fuel pump
Mine is stuck on that double nut link on the fuel line ughhhhh.
Did you ever get it off? I'm having the same problem
Yes I used channel locks on the top nut and a combo wrench on the bottom, and used some penetrating oil. Make sure you are loosening the bottom one by going to the right. It is an reverse thread since it is a fuel line.
2:22 he gives some good advice there. I meant some vice grips on the top nut, not channel locks. Locking plies are definitely your friend on this one.
What size is the locknut?
Me too ....that sucker is over torqued ⚡
I thought i could just go do this, and it starting spurting a little fuel and i panicked and ran back in and booted up youtube >_>

Dude a micro rachet make your life easier to get that torx bolt instead of taking the throttle body off, find the fuel pump relay take it out and crank on it few time instead making a mess spraying fuel every where when your done put back in take few crank to get pressure back up
Easy my ass....that damn screw is a bitch to get off
No te entiendo ni maíz
1) Nonsense. It’s easy to unscrew the bolt and line nut without removing anything.
2) Before working on the fuel line, start the engine & pop out the fuel pump relay until the engine stops. Voila! Fuel de-pressurized.
3) Before starting up, prime the fuel system by turning the key to ‘on’ about five times, then start the engine.
