[Forrider]

hey guys i was wondering if i could use a compression gauge to check the hpop pressure ? plz let me know i dont want to spend no more then i have to i only have 674 dollars i can spend on the truck right now and i want to make every penny spent count im sure u powerstroke owners know what i mean lol

I dont think so, need a gauge that will read or handle 4000 psi. I know the hpop puts out lower pressures cranking and what not, but if it starts and you have a 500 psi gauge on there you will have a big mess and definately dont be holding onto it!

Probably your best be is to put it on a scanner and read it elcetronically. Hopefully you can find a shop that does diagnostics for free.

If you can find one yes, if not a hydraulic gauge should work if ya can find that

I'll have to look but I read a right up somewhere using a hydraulic pressure gauge, a grease gun hose, and one adapter fitting.

Let me hunt around and I'll try and find it, I'm pretty sure it was on this site, or psn

ok thanks guys i apreciate all your help its nice having a site with smart ppl on it to turn to

Bill and Garrett are smart....the rest of us guess real good hahaha

[Forrider]

lmao well u are good guessers and i apreciate your guesses and your time but i have a question i got a haynes manual for diesels well for the 7.3 and it says the compression is 260 to 440 does that mean 260 is the lowest i should see?

[Fordman247365]

Yeah that is pretty close, I cant remember the exact # but 225 rings a bell that if its lower than that it aint enough to fire the diesel
