Hi Will8
I just finished writing a 3 1/2 page article on the Cummins fuel system and lift pump. This in depth article, covers the basics of the lift pump and why it's effciency is VERY LOW. This translates into low fuel pressure at WOT. Article number two will deal with the details, on what you can do to make make your Cummins fuel system more efficient. Having higher fuel flow and fuel pressure will make HP improvements much easier. I hope you like the article!
Feel free to send this article to your diesel friends. I want these tests to be in the hands of diesel owners and performance entusiasts.

Hi this is my first post here! Anyway I just got done with my p-pump conversion yesterday. it was a little time consuming but it was a fairly simple job. I was able to complete it in around 20 hours. The easiest way is to find a 12 valve truck for parts and it is pretty much just a bolt on deal. There are a few mods you have to make like relocating the computer and grinding the head a little to clear the oil supply to the pump but other than that is was pretty much just bolt on. I'm very happy with the way it runs and it should be awesome once i spend some time tuning the pump. If you look around and find parts cheap you should be able to do the job for under $2000 including lines. Anyway just figured I'd put in my .02 worth.

I just did mine in a weekend and all I have in it is a custom PVC intake (made it myself) and about 300$ cause I worked for someone that had a truck with a thrown rod so I took what I needed off of it for free
