Default Fuel Leak...Quick Help.

Last few days I've been smelling gas. But couldnt find anything, today I popped the hood and found the leak. Where the 2 rubber lines comes from near the firewall and connect to the metal lines. There are clips on each line. One of these is leaking, Its damp around there, And it you push on the clip it will leak bad, Is there an o-ring in there or is there an easy fix for this?

Yes, there'* an o-ring. Push down on both the white plastic clips and pull. The white part stays on the metal and the black plastic comes off. The o-ring is in the black plastic part. The HELP! line has the clips and any hardware store ought to be able to get you a new o-ring.

WAIT.

You can't use any hardware store o ring for a fuel area. You must use a fuel rated o ring. If not..the fuel will eat the ring and you will leak again, possibly worse.

Napa stocks fuel rated o rings and the other parts stores probably do as well. Get the right parts... fuel is nothing to play around with.

Right, Fuel rated only.



Your hardware stores don't have those Boosty?

Autoparts stores are closer.

Hardware belongs in the house usually.

And don't drive the car until you fix it.

The car is parked, this has been my backup vehicle the last few months since I got my truck, And of course, my truck blows a head gasket so Im driving the Bonne for a few weeks while I fix my truck and this happens on Easter Sunday. Please excuse my stupidity, I havent dealt with GM fuel injection before, But how do you change these o-rings. I popped the clip last night and looked down in the plastic part and see what looks to be 2 yellow colored rings. Is this what I need to replace and how do you do it?

There should only be one o-ring in there.

You pull the o-ring out by sticking a small pick in there and deforming it towards the center and pulling.


You match the new o-ring by size and rating.
