I am trying to find the correct part number for the mechanical lift pump to put on my M1009 as it has an electric pump. I found Delphi CHFP906 on this site but when I search in internet I only find HFP906. Are these the same or different?
In addition, If I were to leave the electric pump in line on the frame, would the mechanical pump pull through the electric? Would the electric pump through the mechanical? I think they would. I would like to leave the electric in place to use for priming the system and as a backup if ever needed.
