Hello all, new here to the thirdgen board, and judging by my handle, I'm clearly a Mustang guy... but don't hold it against me!

Anayway, I am here looking for help for my buddy. He's in the process of completing his 91 Z28. He has a 350 TPI motor, buncha mods, etc. His problem is that when he was removing the fuel rail, he ripped one of the o-rings "in the part that connects the left rail with the right one." (His words, not mine, I know little about the TPI motors.) The question is, does he need to go to a dealer to get this part, and if he does, anyone happen to know the part#? (his idea) Or, can he just roll down to the local part store and match the o-ring up with one of theirs? (my idea)

Thanks in advance...

Matt

 

buy the fuel system o rings only from gm parts and especially don't buy "hardwear grade" o rings. i've never needed a PN, just tell them what you have and what you want. i always put a little bit of oil on them so they slide in easier and are less prone to being cut. gm will sell you the o rings seperately ,unlike a ford i worked on once, had to buy the fuel line to get the o rings, or i had a really poor parts guy looking for the parts, ended up using gm o rings, since the diameter is basically the same.

 

You can just go to the local parts store and buy o-rings. Just make sure they are neoprene. No problem. Definitely put some oil on them before they go on, it makes the job much easier.

 

Thanks for the responses... A question about the oil. I've heard that using a non-petroleum based lubricant (ie. KY Jelly) is better than using conventional motor oil. The reasoning is that the petroleum attacks the o-ring... is this true, or is it ?

 

I've heard of people using tranny fluid instead of motor oil, but I've never had a problem with the latter. The reason is that neoprene is resistant to petroleum, that's why it is used in fuel line connections, so it will be fine. Think about it, gasoline is going to be touching it anyway.

 

Yea, good point, never really bought into the theory anyway... BTW, i found the o-ring kit on http://www.napaonline.com, part number CRB 218416, for $4.29. Thanks for the replies...

 

well i sure don't know much but i was thinking you wanted vitron o rings and not butal or neoprene.
