View Full Version : Leakdown fitting o-rings

Anyone know what they're supposed to be made of? Buna-n? Viton? something else?
How about the fuel return hose? anything special? I'm about ready to get this done....
Looks like the fuel goes from the lift pump through the leakdown lines to the fuel filter.
I guess that explains why it's leaking fuel...

No one?

I believe the factory ones are Viton.....but don't quote me on that, It's been awhile since I've looked at that stuff. o-rings can be had pretty cheaply online in viton or whatever you want.

Thanks, I was pretty well resigned to going with viton, guess I will.

Finally got off my dead a$$ and pulled off one of the leakdown fittings so I could check the o-ring size, and lo and behold, they're plastic! So I ordered o-rings, fuel hose, and leakdown fittings. Should be here tomorrow....

Had a little glitch with the parts, got that straightened out, finally got the parts put in last week, fixed another problem that cropped up yesterday, test drove today, and WOO HOO, no more fuel leak!!!
