7.3L Powerstroke High Pressure Oil Pump HPOP O-Ring KIT Ford 7.3 Professor Foam!

$ 9.99

7.3L Powerstroke High Pressure Oil Pump HPOP O-Ring KIT From Professor Foam!

Is your 7.3L Ford Powerstroke leaking crankcase oil from the top?

It may appear like the leak is coming from the rear main crank seal, but since the engine valley has a drain - usually oil will drip out of the inspection plate between the engine and transmission. We have found that O-rings are quite possibly the problem.

Professor Foam has the solution! Up for sale is a 4 O ring kit to replace the old, leaking o rings on the high pressure oil pump on your 1994-2003 Ford 7.3 liter diesel engine. This Professor Foam kit consists of four brown or Black viton® O-rings of proper hardness of D70, I am also including 1 (.5 gram) Loctite® 680 high strength retaining compound, and printed instructions included in kit or if you prefer I can email them.

I sell Black and Brown viton® O-rings.  The other guy says that brown is the only way to tell if the o ring is viton, so I guess you must trust him. On the other hand I sell Thousands of O rings a year and I know O rings! So dont believe everything you read on the internet! 

This kit is for the HPOP only. 

If you need O-rings for the fittings to head, inner fittings, and IPR check out my other HPOP kit with 12 O-rings, loctite® and instructions. Not just 10 like the other guys!!


I now have a long thread repair plug as well as a combination kit for the "non serviceable" HPOP plug. Just click below!

 Please look at my other auctions for your 7.3l Powerstroke O-ring needs. 


This kit contains 5 black or brown viton O-rings - color has nothing to do with what its made of, Viton is srtonger and more resistant to chemicals. Someone who is selling o rings that are brown and calling them viton is mistaken, any type of o ring can be sold in any color, so color is not a trate of Viton!
