Those of you that have HPX, where did you get it and about how much does it run? Notice any difference?

Also, I'm going to put in new FPR o-rings and check pressure again before shimming. Anybody have the part #s for them. I prefer to buy at IH but wherever is fine I guess. I just can't find the #s for them. I need the ones for between the fuel bowl and FPR, under the lid held by the snap ring, and on the bolt that holds in the spring.

 

I had a Riffraff HPX on my SD... wish I had pulled it off before I sold the truck. I think they are around $50. Biggest change was a smoother idle.

 

I have the hard stainless HPX on mine (bought it from Oldbird). Smoother idle and the engine is a tiny bit quieter. Just peace of mind really, knowing that oil is getting where it should.

Did you try these guys?
Replacement O-rings for Ford Diesel Engines

 

I saw their bowl/o-ring kit. $12 ain't bad I was just hoping to get part #s so I could just pick up local the rings I need. I use the kit though if nothing else.

How many rings are supposed to be between the FPR and bowl at the screen orifice?

 

Bump. And I checked the RiffRaff site the other day when I ordered my 6637 and it didn't look like they had any HPXs but I could be wrong. There was a listing for one but no link to it.

I'm also still wondering if there's another place to get the o-rings, like IH or Ford

 

take a walk next door to the super duty forum. somebody over there has a write up on how to make an HPX. i just saw it a few min ago

 

Just ordered an HPX today from kcmdieselperformance.com, $55 no s/h.
Look on the main page under "Read First: PSD Part Numbers" will give Ford # and some IH #'s.
Also just ordered o rings today from dieselorings.com, he has a better grade of viton oring than IH.

 

I wouldn't be confident making my own HPX. Not when there's over 3000psi hot oil running through it. I don't want that all over my engine bay!

 

Cool. Thanks guys! Seems like everybody is getting o-rings from there so I reckon thats what I'll do too.
I kinda feel the same but I'm gonna check it out though just in case. I've seen what happens when a HP line blows. Wasn't my truck that goodness but it ain't pretty. Waterproof but not pretty.
