    I tore down the top of my engine today to replace my LIM gasket and UIM & gasket. I am also replacing my lifters. When I went to disconnect the plastic fittings on the fuel line where they attach to the fuel rail, I noticed that when I moved them even slightly, a small amount of fuel leaked out of the rear connection. Can anyone tell me where I can get new "O" rings? I looked into the plastic fitting and can see that there are 2 "O" rings in there. I have read that if you try to get them from a dealer, they will not sell just the "O" rings, but only as complete fuel lines. I only need the "O" rings, not the complete fuel lines. I believe these are "Viton" ??? material.

    Plus, a related question is: Can I just gently insert a small pick or something into the end of the line and carefully pry out the old "O" rings?

    You can get an o-ring kit with like 500 o rings for like $15. Or use a pick take the old ones out and go to the parts store and match them.

    Or I will sell you a full set (2 at 3/8", 2 at 5/16", and a few spares) for $2 USPS 1st class, $6 Priority. (If in US)

    (I bought a large package of each size in viton from McMaster when I needed some, about a 40-lifetime supply )

    PM me

    My car is an '02 GT 3.8 (K) engine, N/A.
    Are these the correct size for my engine? When I looked at the lines, I don't remember them being different sizes. But, I could be wrong since I was pretty tired when I looked at them.
