HPOP keeps blowing an o ring

fordguy_1 · Nov 15, 2016

I don't know much about the HPOP other than it's purpose.

Looking down on it there is a bolt that that is relatively next to the IPR? I think, and I have put 3 o rings on with and without locktite. Part of the problem is that the locktite can't set up because oil continuously runs out of that hole.

Is there a diaphragm or something inside that is bad causing the o ring to blow up?

Do I need to just replace the whole HPOP?

It sounds like you're talking about the non-serviceable oil plug. If so, you shouldn't be doing what you're doing

Check out the kit, and More Importantly, download & read the .pdf on this page -> High Pressure Oil Pump (HPOP) Replacement "non-serviceable" plug on the 7.3 Ford Diesel Oil Pump

I suspect you're talking about the one under the IPR? If so then no that's not the one. I would say it's next to the IPR if that helps any.

Thanks for the input.
