Hi all,
I want to change my stock lift pump over to the piston style pump(3936320). I am having trouble locating one. Can anyone give me some help where to find one. Other than Dodge. Thanx.

 

Try ebay.

 

a local Cummins dealer will be able to get you one.

 

ebay, cheap

 

A local Cummins or Case dealer is where I would go.

 

Thanx all. Found one out of Wyoming for $88.00 plus shipping. A whole lot cheaper than Dodge.

 

case dealership they have them thats wher ei got mine from

 

Why change over ? what makes it better ?

 

The stock lift pump will barely keep up with a stock truck, and when you do pump mods, the fuel pressure can easily be pulled down to zero. With the low pressure piston lift pump, it puts out around 15psi at idle, and can support more than 400rwhp. I know guys with right around 400rwhp, that can't pull their pumps below 10psi.

It's also a good idea to install bigger fuel lines as well. Both of these mods will make a huge difference, even on a bone stock truck.

 

I just put a lift pump in a few weeks ago too. Next time.

 

Do you have a fuel pressure gauge? If you plan on turning your truck up, I'd suggest one, especially with a stock lift pump.

If you don't mind me asking, what exactly is the "Banks Stage 1"?

 

Its just an exaust system, 3" mandrel bent pipe and muffler, I felt a big diff when i put it on. +60lb tourqe they said.

They dont make anything any more for these trucks, seems like nobody does.

 

a local komatsu dealer will get you one i even have part number 6732-72-1350 pump fuel transfer, 6735-71-6610 gaskets 2 required... i dont have the spacer number however. BE ADVISED!!!!! i have not installed this pump yet he crossed the low pressure cummins pump number so i am assuming it is a low psi pump.

 

isn't all of this in the sticky? Maybe I'm wrong... I need to put one in too though!
