The Federal Mogul ES73119 Fuel Injector O-Ring Set is a precision-engineered replacement kit designed to restore proper sealing between fuel injectors and the fuel rail or intake manifold. Manufactured by Fel-Pro, a Federal Mogul brand trusted by automotive professionals for over a century, this O-ring set delivers reliable, leak-free performance in demanding engine environments.

Each O-ring is manufactured to exacting standards using materials specifically chosen to resist fuel degradation and temperature extremes.
