Thread: help with fuel rail quick connects, replacing o-rings

Car is a 2001 grand prix GTP
I am trying to replace the o-rings in the quick connect. Right now I am working on the larger line.
Inside of the quick connect there is a hard plastic spacer and an o-ring is supposed to go on each side of it.
I'm not sure if this hard spacer is supposed to be able to move, but the one in my quick connect does, but I am putting an o-ring behind it, and then moving it so that I can put an o-ring in front of it.

The o-rings aren't very tight/secure in there. They stay in place, but they have some wiggle room.
When I try to reattach to the connector to the fuel rail, it won't connect, and then when I look inside the connector, the o-rings have rolled out of place.
Am I doing something wrong? Wrong o-rings possibly in this kit?

These are the o-rings I am using:
Dorman Products - 800-013

i also had to fight with these damn O rings. make sure the new ones are the same size as the ones you took out. and that plastic ring was free moving on mine as well, i took it out, put the small one in, then the ring back then the larger o ring.


i was stuck and had to buy a box of assorted rings, so i had to match them up.

also when the car is off, the line will move back and fourth when clipped on the rail. when the pump is on it gets tight. but you should not be able to pull it off with out the tool. you'll feel it click when its locked on.

i popped the other line off that wasn't leaking for a reference as well. just to see if i was doing it wrong. played the swap the o ring game for a while and got it back together. no fun the first time out, thats a given.

Well, here's the unfortunate part about trying to match up the o-rings, they disintegrated when I pulled the line off.

You said you put the smaller o-ring in, then the plastic piece, and then the larger o-ring? The channel inside the quick connect is all the same size, so I am putting two o-rings in that are the same size, both of the 3/8" o-rings that are in that kit. One on each side of that hard plastic piece.

its been a while since ive seen inside one. but iirc the small one was the same size as the end of the tube on the rail. it pushed into the narrow part of the line. pretty sure it lived behind a grove where it seats. but like i said, its been a while.

mine also fell apart so hens the O ring swapping game.

It seems to me like the o-rings are too small. They don't fill out the connector, and when I try to reconnect it the o-rings roll out of place.
I bought that Dorman kit in my first post which has both sizes, and I'm using the larger of the two, so it doesn't really make sense to me. Maybe they put the wrong o-rings in the kit?

post 7 has pics of the fuel line and O rings, keep scrolling its there. http://www.grandprixforums.net/fuel-...aking-702.html

Yeah, I've seen that thread.. the pic is too blurry to really see the way they are seated.

I took a pic of the o-rings in there, and I'm fairly confident they are in the correct places, they just seem too small.

in this pic you see how the O ring is seated behind that hump?

thats the hard part, getting it over and seated.




your pic, they look to be in front of the hump.

There's basically one open area inside the connector where I have everything seated.

The yellow you see is the hard plastic part. Then there is an o-ring in front of it and behind it.

if your still stuck tomorrow ill pop mine off and look at it, and take a pic.

Hey man, I really appreciate the offer, and trying to help.. unfortunately I'm almost sure these o-rings they sent me are too small, and I can't find another option for o-rings around town. I have to be at work Monday morning, so I needed to do something to get it fixed this morning.
Not what I really wanted to do, but here's my solution:
