Re: Fuel Pump
after my second fuel pump failure in a few thousand miles, i took the pump apart. it looks to me like the check valves are not staked in and fall out, the diaphram looked fine. i carry an electric pump for backup. i have a new mechanical one also, i think i'm going to take it apart and put some stake marks in the housing around the check valves. if it goes bad again, hopefully the next one is better. i also use only non ethanol gas in this truck. that should help with the life of the diaphram.
