95 hpop

howdy all
My 95 only had 260 psi from the hpop so I pulled it. Now where do most of you buy replacements? Do you use new or remnufactured? I looked on E-bay and some are saying any hpop for a 7.3 will fit and others say that they are model specific. Mine has a #38140A on it, does that mean anything? Any help would be much appreciated. THANKS, Montana Gambler

Using a later pump will cause an oil drain back issue it the timing cover is left unmodded. So after a long sit (day to a couple days) you will have a hard/no start. A newer pump (17* from a 00-03 7.3) will provide higher capacity to keep up a chip or larger injectors to a point and set the check engine light less often.

Here is the cheapest place I have found for new pumps. for the direct replacement just get the one for ythe 95 if you want the higher capacity and plan to do one ot he the mods get the bottom pump

BTW I hope it is the pump cause there are a number of other issues that can cause low pressure that a new pump won't fix. Unless you are positive it the pump it might be a good idea to put it back on and do some testing with us.

Thanks for the reply, I'm hoping for the pump at this point. I pulged 1 side of it and put a pressure guage on the other, thats when the best I could get was 260 psi. I put new O-rings on the pressure regulator and got no change. I took this truck to a dealer last year, they couldn,t get codes except the cam sensor, it has the 3rd new one on it now, tack moves. Put on rebuilt idm and nothing. new fuel pump and filter, gets lots of fuel. $2400 later and they said they couldn't make it run. Mike

Do you plan on any performance upgrades or have any at this point? That will help decide which pump you want to get.

thanks again, The shaft nor the gear were scored, is there any way to tell about the gear slipping? No mods for this truck, just want it to run. Its in very nice shape, Ive had it for 8 years, but it is a work truck-used to pull great.

It was probably no a loose bolt. That is very rare and generally only happens after someone has just reinstalled the pump.

I would just get the stock replacement pump and a new IPR. That will take all the guess work out of it. It those don't fix it you have a control problem between the PCM and IPR.
