HPOP Questions???
Hey i've got a 95 f450 powerstroke and ive done some research on this but am not clear but what i need to know is if I put a new HPOP out of a 2000 model 7.3 can i just swap them out cause i really dont like the idea of all that anti drainback talk its looks complicated and for the record i have installed ad splitshot injectors about 6 months ago with a new hpop however it seems to trip the cel under a load for an extended time so i want to put the newer pump in and hopefully fix that and have a little better power..any tips would be greatle appreciated

You can't just swap a 17* into a 95. You either have to modify the front cover, or have the 17*guts swapped into a 95 case. If you do the latter, it will go right in.
Take my word for it. I've done more hpop's than I a care to recall. And I actually tore my truck apart to actually do the machine work on the front cover so I could be done with it. But I aborted because the only solution is a self tapping screw and rtv in your front cover. Unless you can weld aluminum upside down and in a mirror to see it. I can't, and I didn't want a screw in there floating around.
So option B. I sent my 17*, and 95 15* pumps to Joey at Terminator Engineering. He swapped out the guts for me and modified it in the process. Problem solved, more oil, no drainback. If this option interests you, email Joey and tell him Cody from Death Row Diesel sent you. He'll hook you up. And trust me, it's cheaper than you ever thought it would be. It's worth the email. Good luck man, and I hope that helps.

so are you saying that the sd pump physically wont fit in the truck or it will just be hard to start after sitting because of the anti drain back issue. and its a tow truck that i use daily and so when i start working on it i have to have parts ready to go in before i start otherwise sending them off wouldnt be an issue..and if it will bolt in what other issues will i have with it by not doing what you suggested

The SD pump will bolt right in. They are exactly the same dementions. It will be a hard start, or no start after sitting. And if you have the 17*, you can just send it to Joey and tell him to put it in a 95 case with the drain back valve. He should have some on hand. Not sure how much extra that will cost, but shouldn't be much at all. The only other thing that you will have to change is the high pressure line fittings. Just swap you old fitting on the new pump.
If you don't send it off and just put a normal 17* with no check valve, it will just have hard start issues...........Now, that being said out of all my times of doing these pumps, I've never just "done it" to see what will happen. I base that on what the experts tell me. Experts being pretty much every person that modifies, or builds these pumps.
However, if you are so inclined to just do it and see what happens, I'd be VERY curious to see the outcome.

Another option would be the Adrenaline HPOP that the Dieselsite sells.

So, after sitting, the HPOP should loose oil your saying?
I guess I'm confused, I'm not seeing this issue with my vehicle.

Just wondering if that's why he's throwing codes, because his programing can't run the splits...

The AD's require more oil to drive them. Its why the factory increased
the flow of the pump. The 15* was fitted to AB splits oem.

ok i follow everything you all are saying about running a factory pcm with ad injectors and it being a possibility that programming is an issue however it will run the ad's just fine but not to the injectors full capacity cause of the smaller hpop and the programming, but i had the injectors installed and they made plenty of power without ever setting the light but then my hpop came apart internally and sent tiny particles of metal through the ipr and made it to one injector so i had to replace the injector, the hpop, and the ipr all by ford but ever since that repair was made it been setting the light for a p1012 under a heavy load and has not has its full power back in every day driving.. i even changed the oil every 2000 miles for the next 4 oil changes after and cleaned the new ipr just to make sure all the metal got out of the engine so sorry for the long post but thats whats leading me to believe that this particular hpop is either bad or weak right out of the box and if im gonna change it i might as well upgrade it in the process....Also im pretty close to the ford guys at the dealership i do all their towing and they agreed to warranty the hpop and give me the one for a 2000 ford at no cost. but im not sure at this point what to do
