Painmann,
I have, as well as others, used the '05 cummins in-tank lift pump (Sorry, can't find my invoice for the part #). It is almost identical to our in tank set up except for the addition of the pump itself. I think there is a write up in the tech section. I went with the in-tank set up as I drive a lot on dirt roads and didn't like rocks and such pounding on it. The installation is very simple (Tank as empty as possible, floor jack, and a piece of plywood to distribut the weight of the tank on the jack). Lower the tank slowly, you will have to reach up and disconnect the fuel lines, and lower. I used a brass round punch to remove the ring holding the pump module, cleaned up and reused the green o-ring. and replaced. For the wiring, I went to the auto parts store and got the wiring plug inserts. Before leaving the wiring under the seat and sercuring everything, check the polarity for the pump by cycling on and having the vent on the fuel head open with a tube to a container. All in all, it took less than 3 hours with a buddy helping and less than a sixer between us.
I have not had any problems with the set-up, and really like the ability to prime on fuel filter changes.
you will have to change the fuel level rods from your orginal to the new replacement for proper fuel level.
