I just installed ( with the help of a professional mech.) a 40223 Duralift elec. fuel pump on my 91 7.3 I.D.I. My truck had become untrustworthy. Sometimes it would start and sometimes it wouldn't. I thought the fuel filters were the prob.,but apparently it was the mechanical fuel pump not working properly. I copied and followed DesertBen44's directions for the installation. I want to thank ALL of you that responded to my plea for help.
