Greg, consider what needs to be done when a fuel pump fails to return to operation. For the purpose of this discussion we'll assume all the necessary replacement parts, testing equipment and tools are on board. General fuel system leaks are not included because their repair is the same for either type of pump.
Electric pump, OPSS failure
Jury rig = jumper the OPSS terminals
Complete repair = replace OPSS
Electric pump, pump failure
Possible jury rig = dislodge stuck ball under bottom cap
Complete repair = replace pump
Mechanical pump, diaphragm failure
Jury rig = none
Complete repair = remove and rebuild pump or alternatively replace pump, change crankcase oil multiple times
