HPOP Questions

Well I found out today my HPOP went south and it is at the Ford dealership now. My question is whats the benefits of doing a stock over a aftermarket pump.. I am currently running a ts 6 position, exhaust and DIY intake. I have no plans going big injectors or anything like that. Next question is how hard to install is it.. is there a write up anywhere or is this something better off left to the professionals.. What all needs to be replaced when a HPOP is replaced

I have not quoted a stock replacement but based on how bad they typically are an aftermarket one is probably the better deal. It seems even with stock setup people see some minor gains with the aftermarket ones. I think this page has some good information and he is a good guy. I drove up to his place one time to pick up some things on very short notice. DieselOrings: High Pressure Oil Pump reseal kit - 7.3L Powerstroke

Get a t-500 from terminator, $450. Not hard to do. You'll need 1/2" socket with a short extension for the mounting bolts on the fuel bowl. 9/16", 5/8" & 3/4" wrenches for the fuel lines. I would get the orings for the fuel lines too. You'll need a oil line disconnect tool for the hpop lines and disconnect them at the pump. Then you need to remove the ebp line by the sensor, two 5/8" wrenches, a stubby wrench works good once it's broke loose. Then you have 2 bolts to remove the access cover (8mm) go with a screw driver and pry it away and clean the old grey silicon off. Then remove the drive gear bolt (18mm) with an extension, I break it loose the spin it out by hand kind of a pain because there is a coolant hose coming off the top of the water pump. Then two bolts mounting the hpop to the front cover 10mm and its out. You can also remove the hpop resivior to see the gear and bolt for installation, I would remove after the hpop is out so then all the oil will drain down the valley, it will be messy. Put a drain pan under the dust cover where the tranny bolts up to the engine. I would also get a new ipr too and a hpop mounting gasket, and IH gray silicon for the access cover I think that's all. Anyone feel free to add if I missed something

They are fairly easy to replace. The post above mine pretty much covers it.

We carry the Terminator T-500 HPOP if you are interested.
