My fuel return is leaking where it attaches to the fuel filter. We had it off a couple of times during an injector install. Can't realy tighten it anymore without over torque.
Can those silly rubber covered washers be replaced with more easily available plain copper or will I strip it if I try to torque down a copper washer?

 

I suppose you could, but as cheap as the correct washers are, why?

I reuse them once, then they get replaced, under a buck each IIRC.

 

Yeah I suppose, but its a 20 mile ride, 3.00 dollar part vs a few blocks 10 cent part ....found some gasket material I'll cut my own..

 

20 miles, thats shorter than my drive into Cummins in the city. I thought you were furthere than that. Just go get a handful from Cummin's. You're gonna have trouble cutting washers out of gasket material.
