Serviceable Long Threaded HPOP Plug for Ford 7.3L (94-03)

If your "non-serviceable" plug at the bottom of the HPOP is leaking, it is probably due to the factory short threaded plug has stripped the threads from the aluminum HPOP body.

The replacement plug is a 'long threaded" plug made from high quality 303 Stainless Steel and is machined to the exacting Navistar standards. This plug can successfully repair a HPOP "non-serviceable" plug that has completely stripped out the factory threads.

The Serviceable plug comes with a new o-ring and a .5ml packet of LocTite 680 Retaining Compound. 100% Made in the USA

    All parts worked as they should,

    But be mindful about the little ball bearing as I had the HPOP in the wrong orientation and the small ball bearing came out. So with IPR removed its easy to get back in position to then install the kit, so easy to Take your time, dont rush
