...Just ... a couple 25 cent O-rings..
ain't that what Morton Thiokol said
Nitrile and Buna N are most common for petroleum products with low aromatic content and probably what’s been working well in that fuel rail for 15-20 years. They'd be fine with 10% ethanol as well but if you’re running exotic fuels or methanol, buy fluorocarbon elastomer (aka Viton if you’re a DuPont disciple). It’s only ~40 psi so not a particularly demanding fluid sealing application but if you're not comfortable selecting an O-ring based on the gland size you shouldn’t be fiddling with fuel systems……However, it isn’t rocket science.
