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.
