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 exclusively for DieselOrings.com. 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. Made in the USA

  7. Good product so far 5 Star Review

    Posted by on Nov 7th 2015

    We recently had another customer with a 7.3 come in with a major oil leak and found that it was the "non-serviceable" plug on the bottom of the HPOP. Before we knew about this product, we matched up an o-ring from NAPA. We informed the customer that there was a chance this would not work in the long run, but he opted to give it a try to avoid buying a pump. The o-ring held up for about two weeks, but it failed. So far, this one has been good. The customer is happy, we are happy, and we now have an extra on hand for next time!

  8. Finally no more leaking. 5 Star Review

    Posted by on Jul 23rd 2015

    I started in the back. Did turbo o rings on pedestal. Did the simple orings on top of hpop with new fittings. Also did a ipr oring. Finally decided I had to pull the hpop. Ordered this plug and a mounting gasket. Once I got it out it was obvious this was my leak. The o ring was hanging out the side of the plug. Ran about 100 miles so far. Seems to be no leaks now.

  9. Better than the original one. Longer threads. 5 Star Review

    Liked the quality and the instructions were really easy to follow! Thank you for the awesome products you sell n the installation manuals, they're invaluable.

  10. non-servicable plug 5 Star Review

    Posted by on Aug 7th 2014

    The product was just as described. It came with everything needed for an easy install. The pic is a bit deceiving as the plastic sleeve covers the threads but rest assured it is exactly what is needed.
