Here you go guys and gals. A 10 minute video explaining the entire fuel system of the 98.5 to 2002 Dodge Cummins. It shows operation of the lift pump, filter, fuel heater, VP44 and injectors. Someone really out did themselves on this video! http://s1094.photobucket.com/albums/i443/TannerSpangler1/?action=view&current=Cummins_ISB.mp4

Now that Ive seen all the parts in the pump I am totally convinced you will never get a complete rebuilt from anyone.

what they dont show is the return galley to the rear banjo for injector cooling.but this answered about a weeks worth of research to understand the fuel system

Thanks Mike. That was great. There is a lot to be said for seeing it that way, for me anyway.

That was good Mike. It backs up what i have learned here about the fuel system. I appreciae it.Do they have one about what the fuel does inside of the vp?

I snagged that from Competition Diesel forum...I saw the movie and was very impressed and thought about you guys here so I brought home so you all can enjoy...
