Fuel line "O" Ring size

[dssranger]

The Duck bill clip on the fuel regulator has two O rings that connect into the fuel line, does anyone have an idea what size these O rings are? The Auto parts store wanted to sell me a univerisal pack, but the size on O rings is very important to guess, I think anyway. I have a little nick on one and want to replace it. Thanks for the help!!!

You wouldnt be guessing....you would find the best 3 candiates out of the pack, hold the old one up to each and narrow it down to the right one. Make sure they are made out of a material that can handle fuel
