I'm leaking oil from where the injection pump mounts to the case, I've had this pump out 4 times, changed orings, used silicone. I've slowed it down but it still leaks. I'm beating my head against the wall. Then sometimes I'll it will hardly leak. The only thing I can think of is the valve...

I took my injection pump off my truck yesterday and when I put it all back together and took it for a spin I noticed it was really laggy, it ran fine before but now it takes for ever to build boost like if I stomp on it in 5th gear it would go to about 10 and just hang there. So I'm thinking I...

Used air dog 2 165, just p pumped my truck and pressure wont go high enough for what I want so I bought a new one. Figured I'd try and sell the old one. It was set up for a tank with a sump. About 30k for miles on it. Asking 450.

Gotta vp44, come off a school bus someone was partting out and had a Cummins in it, motors gone still got the pump. Has 160k on it. Not sure if it's a ho or so. Motor was hooked to an AllisonTrans. Asking 450.

Just finished my p pump conversion, finally working out the bugs. I have the billet timing cover and didn't wanna lose the breather there so I drilled out a 3/4in hole on the adjustable timing gear cover, put a 90 on it with a house running to the back of the motor. Yesterday I took it out and...

Goodd used vp44 for sale not sure on the millage. Truck had 100k when I bought it and now has 150k, has had a air dog 165 hooked to it since the day I bought it. Nothing wrong with it just p pumped my truck and don't need it. Also have the lines and the gear. It is a reman pump. Asking 450...

I got an 01 that I just p pumped and now there's like a slight vibration from the motor. Could it be coming from the 7100 pump? I had the harmonic balancer off a couple of times and took a wire wheel to it to clean it up, is there a certain way they go back on? I also read somewhere if you have...

Just p pumped my 01 and when I rev it up it sounds fine but when it idles back down its kinda like it's got a hiccup right when it hits normal rpm idle. It's had to explain. I was wondering if the .84 lines had some thing to do with it. I have a video of it but can't figure out how to up load...

OK I've searched and searched and I'm not sure on this adjustable timing gear, so I'm just gonna make a post, I have a 01 that I p-pumped that I'm putting back together so I have the timing cover off and I'm standing in front of the truck looking at the pump I turn it (clockwise) to advance the...

First off I think I'll have better luck here so that's why I posted in the 12v section, Getting ready to p pump my 01 I got a 215 pump, 4k governor spring kit, 191 dvs, mack plug in the back, custom fuel plate. 84 lines... I heard that the 24v head runs cooler so you can get away with more fuel...
