I have an IP27 with a Yanmar 2GM20. I have a 12 volt Fuel Pump between the Racor and the Mechanical Fuel pump on the side of the engine. The 12 volt Fuel pump has gone bad (runs Continuously) (Stuart Warner $ 235.00). This is the 2nd pump in 5 years(400hrs) that went bad. Could I trash the 12 volt pump and go with a Squeeze bulb? Is this a good idea? Or could I use another pump of some kind? I really only need it to do my filter change right?
