95 7.3 PSD HPOP & IPR

[KirkG]

Hi All,

I am looking to replace my HPOP, but I am new to Diesel. Is it very difficult?

Where is a good place to buy the HPOP for my model year?
Should I try and replace the IPR valve first and see if that solves the problem?

The mechanic I took it in to get it diagnosed is wanting 500-800 for the part and I'm looking at 1,200+ to get it done there. Looking to learn a thing or two and save some money at the same time.

Thanks for your help guys!

Diesel newbie here too. Not real difficult, but a little time consuming when doing it the first time. A lot of guys upgrade the hpop and there is a lot of info using the search button. You will have to remove the fuel bowl and associated fuel lines to get at it, so you might want to plan on replacing the rubber lines while your in there. My 96 had both an oil leak from the hpop and massive fuel leak from dry rotted lines. Because I plan on keeping this truck for a long time and am planning a cross-country trip with it, I went a little overboard. My fuel bowl was in pretty bad shape overall, so I just replaced it completely with a new one. Also went with a new fuel pump and did a complete re-seal of the hpop. Valley is dry as a bone now. I got all my stuff from Bob at dieselorings.com. Great guy to work with and excellent prices with fast shipping. Highly recommend him. Hope this helps.

theres a inspection cover on the front engine cover. Remove it and the bottom hpop bolt can be removed. Dont drop anything in there, or you will be pulling the engine.

The hpop is a huge pita. It is on the super duties, anyhow.

First, what's the problem?

^Ya good question... what did the mechanic do that tells him the hpop is shot, and whats the issues with the truck?

Sorry I didnt see the new posts earlier... The truck would lose pressure once the oil got hot and thinner and would not start. You had to let it sit for 3+ hours and give it another try and then it would start. Replaced the HPOP and the problem is fixed. Thanks for your help guys!
