I am putting the fuel lines back on after having to replace the oil pressure switch. I have leftover Fel-Pros from a MS98002T kit and I bought a BWD 27478 from Advance. After looking at these one-on-one, the Fel-Pro smaller o-ring looks noticeably thicker. See Attached.

Any worries here? The BWD bag numbers don't match the BWD box number (27478).


I now believe the BWD 27478 set is meant for a fuel injector. The listing Advance had on their computer was not real helpful description-wise; I should have checked their website before going.

Captain Hook, I have a 96 4dr 4wd. The top fuel lines, that go from near the firewall to the top of the upper plenum, are removed. Are these the 5/16" & 3/8" you mentioned and I would assume I need a set for each end?

 

Fuel rated O rings are brown. You'll need a 5/16" and a 3/8"
