What type of electric fuel pumps are everyone using? Have replaced manual pumps with Carter marine rotary pumps and have them mounted near fuel selection valves. They constantly get warm and vapor lock requiring me to cool them with water before I can get back under way. The boat is a 88 300 weekender with vortex 5.7s. I've replaced the carters with an aftermarket mercruiser pump like the ones run on an 1994 4.3 and 5.7 but they do not last, have burnt up two in less than two weeks and are now removing and returning,. Thanks to a lifetime warranty on the pumps. Anyone have any ideas or advise? This is driving me crazy. I had looked into the Holley Red Marine pumps, but they say they have to push and I cannot gravity feed them through an anti siphon valve
