(1) For a fuel transfer or lift pump. The transfer pump is kind of like a 1970's gas engine fuel pump. This pump is located on the left side middle of engine. Disconnect the batterys (Both). Remove starter. Place a drain pan below the pump. Remove the both fuel lines. (May have to loosen other end of the steel lines). Remove two mounting bolts. Lower pump down. Take note: some Cummins engines have a spacer between the transfer pump & the engine block that requires two gaskets. Not to sound short for this part. (2) For an injection pump. There is a lot of timing issue here. Take it to a mechanic that you trust and is a cummins tech or get a factory manual (Dodge or Cummins)
