Nylon fuel line help needed

[Mister G]

If you did want to try some o-rings, you could go to Harbor Freight and buy their green o-ring kit and see if one of them would fit. I would be leery of any universal o-ring unless it specifically said it was made of Viton rubber. This ethanol fuel we get at the gas station is hard on rubber parts. Buna-N are decent for oils, but not as good as the Viton or HNBR rings in the green kit at HF for ethanol.

I greatly appreciate your help with this matter. The fuel leaks so bad that I do not start the truck out of fear of a mishap.
