Ok, I have had my fuel lines pulled off my fuel rail many times, and I am wondering if I should replace the o-rings on the inside of the female connector ends where the fuel lines connect to the rail? Has anyone else replaced them? If so, what is the part # for them? Thanks!

Hmmm.... crap. GMPD'* catalog is down. I think I found them. The dealer called them "Fuel line o-rings". I will wait for a PN# from someone to confirm these are it.

You shouldn't need to replace them until they begin leaking. I've pulled my fuel rail off the lines about 15 times.

(BTW.. guess what'* getting shipped today? )

Ok, that'* what I figured. They don't leak, I know that.

And YAY! My big whining chunk of metal!!!
