Specs At A Glance

Good To Know

Q: Does this fit my vehicle? A: It fits fuel lines with a 3/8 GM quick connect and AN6 plumbing, so check your connector size and thread before ordering.

Q: Is sealant or tape needed? A: AN and quick connect fittings seal on their mating surfaces, so keep threads clean and torque to spec rather than relying on tape.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
