I have an early 02 2500 ram 4x4 dually that I love dearly. It would run good and then die. Ran the codes it said injection pump. Changed injection pump and lift pump, same problem it's not getting fuel. Ran hose into tank plugged it into the lift pump problem went away! I have tried to find a sending unit w/out pump but they don't offer them anymore.:thk: What are my options?
