Like Drew mentioned, you're probably talking about the fuel Ts. There are eight o-rings that go on them, and for some retarded reason, they never come in the kits. Not a single kit I have ever seen anyway.

You can get by temporarily with white teflon plumber's thread tape, but it's by no means a permanent fix.

Most dedicated auto stores (Napa, O'Reilly's) keep a box of green AC o-rings in the back that are made of the stuff you need for gas. Take the T's with you, and you'll want as close to 2x8mm as possible.

I'd rather give someone a tool than a solution. Give them an answer and they'll always expect it. Teach them how to find the answers for themselves and they will spend a lifetime learning.
As for my mental state?
