Where can I get the orings for the gas tank?

Looks like two are the same size (fuel sender and filler neck), and then
the main gas feed/vent at the top is slightly smaller.

Please don't say "go to a parts store". I actually work in auto parts and have searched high and low at my store, plus my competitors with no luck.

Everything is either the wrong ID/OD (and ends up leaking, or breaking the O-ring from being stretched), or is too thick (cross section) so I can't get the lock ring in place.

I found one that I *might* be able to make work for the gas feed at the top, but not the others.

Does anybody know what the exact dimensions of these should be? ID/OD and cross section.

Please advise guys! I know someone has replaced these things!

The original parts are non existent. I tried ordering them through a friend that works for Toyota before I made this post.

I ordered a bunch of similar sizes online and tried them all. Found some that work.

For future reference and searchability:

http://Www.theoringstore.com

#B70331 x 2 (please note you have to order at least 4, though, as the manufacturer has a minimum order on each number). This size works for the filler neck and the sender.

#B70329 x 1 (again, you'll see a minimum but they're ridiculously cheap). This size works for the center/top feed/return line unit.

Hope this helps someone in the future.
