View Full Version : O-ring for fuel rail?

12-18-2007, 03:34 PM
Alright well the last couple days ive been on xmas break from school. So i decide to do my LIMs. Yesterday i started and today i finish things up and put things back together. Go to start the car and i have a bad fuel leak. Its coming from the read fuel rail/fuel line.. Now the O ring was put back into place,upon further inspection i look into the rail with a flash light and notice about an inch to inch and quarter in a dougnut type ring where the fuel line mates inside the fuel rail. I look at it more,and it look like half of the ring inside the rail is missing. I dont know if this is normal or what. If its not,it would explain the hardcore fuel leak i get. Also is there anyway i can just buy one rail? and not the whole set up? Thanks in advance

You can just run up to the local parts store, and in the HELP! section, they should have a package of O rings. Those will work fine. It may have been hesitant to start up because fuel wasnt at the injectors right away from the rail being open. Just my guess.

I have a general assortment of o-rings and I just used the one that best fit. The actual size someone's posted here before I'm sure just dont feel like looking for it at the mo

youre gonna pay a bit extra, but go to the dealership. they will know exactly what you are talking about and will give you the right o ring. i had to do that for the coolant bypass thing that plugs into the water pump. i paid like six bucks but i think it was worth it.

the one from the dealership is 20 bucks and you get the oring for the fuel pressure regulator too.

when i needed one in a hurry i got one from napa that held up till i took the engine apart to do the lim again. paid like a dollar something.

heres the part number for the dealer one if you want it

happened to me as well. took a few weeks though. fuel was shooting out right next to my alt. thats kinda scary. turned out to be the little damn o-ring.

Same thing happened to me. I tried the o rings at the auto part store, but none of them fit quite right, so i had to get it at the dealership. I think it was like $12, but I guess its worth it to not have a leaky fuel line and not have to screw with it.

12-19-2007, 12:11 PM
k well i went to the dealership. Got the two rings for $20...put it on,car still leaks...took it out to find the ring had ripped again. Idk what to do.Are you guys sure that the inside of that fuel rail is ok?? this is really pissin me off

12-19-2007, 12:16 PM
you got to be real gental when putting it in your probably ripping it on the threads. its a real tight fit.

how far back does it go? i think that may be my problem...idk how far back it goes into the rail

k guys update...i ended up buying another seal kit;crap and it worked this time around. The car started,ran rough for a few seconds then smoothed out. It threw a TPS code,which im not worried about,but the damn guy at autozone wouldnt delete it for me, he said its a new thing they do? which is new to me. Anyways the car held at 185-195 and ran smooth. Tomorrow i have a oil change planned to get all the crap that was accidently dusted in there during the process. ps does anyone have the part # for the EGR gasket...where the tube goes into the egr valve itself?

12-19-2007, 05:13 PM
there isnt a gasket for where the egr tube comes from the manifold into the egr.
but theres a gasket for where the egr meets the intake.

12-19-2007, 05:21 PM
i could have sworn there was one....

12-20-2007, 06:29 PM
yea when i did mine, i just left the egr on that tube and just disconnected it from the manifold. did you take yours off that tube? i dont think its necessary.

12-20-2007, 07:20 PM
yea i did...everything is good today..got around to do an oil change and everything. I also too care of the TPS issue i got while doing the LIM...car seems to run smoother than it did before

never noticed one on any of the cars at the yard. honestly i dont think theres one to begin with.
there wasnt on the one i took the plenum off a few weeks ago.
its not like the pre 2000 setups where it needed the gasket on both sides.
if you want you could probably make a gasket for it but its not really needed.
