#8-079 HPOP DISCHARGE HOSE FITTING O-RING 1999-2003

Seals the high-pressure oil pump discharge fitting to the pump body.

This is the exterior/boss O-ring on the fitting that threads into the HPOP.

Note: The fitting threads into aluminum and require threadlocker. We recommend Loctite 680 (one 0.5 ml packet per 2 fittings).

Includes: 1 × Exterior O-ring

Order quantity of 1 = 1 O-ring (enough for one fitting). Most trucks need 2.
