Im haveing a fuel leak on my rail, i guess the crush washer gave up. I was wondering nylon washers will hold, even though its use for oil? Just want to know if it will hold up fuel before i try it.

 

I wouldn't recommend nylon. Over time the gas might eat it away. You should be able to find some at autozone or checkers. They have those washers in like 4 packs or something.

You should be able to use copper washers also.

 

i guess ima use the nylon for now as long it dont leak. Ima take a trip to autozone.
