Location: Tennessee		For an Onan generator (7000 Margold) what is the required fuel pressure needed. Our generator has two fuel pumps because of its location on the roof in relationship to the gas tank. The top fuel pump is not working and my husband is looking to replace it and wondering if we have to go with an Onan pump,

Location: western PA		Almost any auto parts stores sell after market replacement electric fuel pumps, or they are readily available on line. You will only need one with a pressure of 7 - 8 PSI and a max flow rate of ~ 20 GPM. They typically cost ~$50 - $75 and should be mounted near the fuel tank pushing the fuel to the roof, whilst not trying to suck the fuel at height. They typically are wired into the run side of the gen's wiring so they are on only when the gen is running. A momentary switch can be installed that would allow the pump to be manually over ridden and used as a primer for atarting if necessary.
