I’m going to swap a Cummins into my 97 f250hd and replace the 5.8. Will I be able to use my in tank fuel pumps to run the Cummins.

 

Hi, The intank pumps can be used, but you will have to put a pressure regulator in the fuel line. A VE pump (rotary injection pump) can only stand a maximum of 10 psi without blowing the front seal. A P7100 (inline pump) can stand higher inlet pressure. One of the Cummins swap sites will have all the information you need. Brad.
