i have been play with mine and 28* of timming works the best. i was just wondering what anybody else was running.
could you make a thread or somthing about how to install a p-pump. i think that would be awesome.

or at least tell us about the install, parts used, and time it took to complete.

that would be really cool. thanks.:popcorn:

You won't need an ECM anymore. If I'm not mistaken???

YES you will need the ECM. with out it your tech will not work. with out the tech the pcm will not know if the motor is running of not. If motor is not running you will not have AC,Att will not charge, and tranny will not shift if it's an auto. tech,oil pressure, and water temp gauges all run thru ECM. so on a 98.5 to 00 you will need to have the crank senser hooked up( the one down behind the starter). on 01 to 02 you need the cam senser hooked up(under the vp-44 on timming cover). that is what makes your tech to work. the only thing not need any more is vp-44 wiring. auto trucks will need to keep APPS senser working for tranny controls. 5 or 6 spd truck will not need the APPS any more.
parts need are.
12v timming housing (alum housing that mounts to block)
p-pump and likage.
fuel lines ( pump to head).
pump support bracket.
pump drive gear.
All parts are cummins parts. ex fuel lines.

To do this in the truck it will take 8 to 10 hours if you know what your doing. there is a lot of work to be done. remove all of the stuff on the front of the motor, then remove cam. replace timming housing. then put it all back together. you have to remove Rad,intercooler, bumper and move ac condeser out of you way. it's not some thing you want to do if you not ready for a long weekend.

why does the camshaft need to be removed? is this because of installing the camshaft with the lobe for the mechanical lift pump? and for my last question:lol3: why cant the original ecm be retained? i'm not disagreeing with anything i'm just wanting to learn as much as i can.:thumbsup

1. the can needs to be romoved to change out the timming housing. there is part of the alum housing that go behind the cam gear. so the gear needs to be pulled just to change housing. you can put the stock cam back in or use a 94-98 12v cam for lift pump lobe if you like. most guys who do p-pump swaps will run big lift pumps like FASS or Airdog or something.
2. the stock ecm is retained. the only thing you will not use from the 24v parts are the VP-44,front cover,gear,and fuel lines. the only plug of the wiring harness that does not plug back into some thing is the VP-44 plug(the big black sliding plug on the back of the pump). you can just cut the plug off or hide it some were.
3.i will go take some pics and post them up in a little bit of what needs to be done.

when pulling the cam out could one just pull it out far enough to put the new timing cover in?

What are you looking at to find that 28* is the best. EGT? smoke? Just woundering thanku.

Yes and no. To get the cover to clear the cam, it will have to be pulled out far enough that the lifters will all have to be raised up anyway. May as well pull it all the way out and get it out of the way.

Timing will depend on alot of things, but the biggest thing is what you plan to do with the truck.

Oh and I would recommend not cutting any wires. I am in the middle of a VP conversion. I converted a truck over to a P-pump for a customer. He is doing something different with the truck, and part of that is putting it back to a VP. I left all the wiring there, just zip tied it together to the harness so it would be neat. Now I am glad I did. He was wanting to rip it all out to get it out of the way when I did the P-pump conversion.
