Description

These are a handy item to have on hand if you find yourself servicing performance fuel systems or if you are installing a new fuel rail and want some insurance in the event you damage an o-ring during an installation. These are size -908, which is the specification size for use with all -8 ORB fittings. The material is FKM, which is the ideal material for use in both gasoline and ethanol systems, as well as gas/ethanol (e85 etc) systems. Among the aftermarket parts community, -8 o-ring boss (ORB) is among the most popular size of port used on fuel rails and fuel pressure regulators. Of course, not all fuel rails and regulators use -8 ORB, so you should always check your size requirements before ordering. 

Each pack of o-rings includes 5 o-rings total.

    Sebastian J. ★★★★★

    Exactly the right size for my -8 ORB fittings, and the FKM material holds up great with E10 in the tank. These five rings saved me a trip to the parts store.

    David ★★★★★

    Put these in my fuel system and no more weeping at the o-ring boss connections. The FKM holds up fine with the E10 blend I run, no swelling or hardening after a few months.

    Evelyn Q. ★★★★★

    Swapped these onto my -8 ORB fuel fittings and the FKM rubber handles ethanol blends without swelling like the old ones did. The 75a durometer feels firm enough to actually seal. Five in a pack means I've got spares for the next project.
