Try this, I used this number and it was still good. The price might be as high as $160 retail it depends on the dealer. This is complete with all gaskets and a light kit also.
1) If you need to replace your lift pump, try ordering Cummins PN 4090046 from a Cummins dealer, not Dodge. It is from what anybody can tell, the same thing as a factory lift pump for $65 vs $200. Do not ask them any stupid questions like "Will this fit on a Dodge. " If they ask, it's going on a school bus.
