Here you go gang... How to remove the VP44 the quick and easy way. Takes approximately 45 minutes for me to do this much.

 

Remove the Mopar1973Man Crankcase vent (if applicable)

Using a 10mm socket remove the air horn bolts and dipstick bolt.

Now unplug the VP44 main connector and wire tap . This connector is a two step plug lock. Pull the release tab and wiggle the plug out then pull a bit more on the release and the plug should release fully.

Pictures are always a PLUS.  What did you decide to do about the wire tap on your new VP44?  If I remember correctly, DAP sold a pump that allowed for a tap and a 1 year warranty, but it was a little more money.

How often do you even use wire tap now with v2 stuff, I personally realy have no need for it anymore, maybe just to screw around.  Especially if you're going for mpg. With your bigger injectors and hybrid you may not need to tap it at all.

It true I do have a power bug. BUT! I do know my limitations and how far I can go. I'm not going to do like @TFaoro or @jlbayes that is way beyond my needs or wants.

We all knew he's had it....  Now he admits it!

 

I've always had it. I'm not going to deny that but my requirements are MUCH less than most. Actually, the MPG is the priority over the HP and TQ numbers.

Can't go back now denying it, it's on the record:burnout:

 

Nope. Not going to deny or go back. :burnout:

I love the feeling of grabbing a gear and the tires just ripping loose under the truck. Also fun to blast those puppies in Boise that think they got something and you eat them alive from light to light.

At least you can see yours!  I haven't heard anything back about mine that was sent for warranty...  Sure hope it's on its way back.

After a week of sleeping in the garage the lazy Cummins didn't want to wake up. I ran the batteries dead attempting to get it to fire up. After fighting for a good 15-20 minutes I finally got it to light off. Now it does run I'm not seeing the wild lope I had before nor am I getting that wild aggressive timing any longer. I've only made a few short trips here locally which was getting a tank of fuel and taking out the trash. So I'll see what happens after a long haul.

Hopefully you get better mpg's and start playing with some tunes. They say when vp's wear out mpg drops.  My last tank playing with different tunes got me 15.4 hopefully just heavy foot...
