Buy a cheap electric pump and it will last about as long as the 3 month warranty. Sometimes it won't even make it that long. I had one die after two weeks.
I've solved the problem by buying the best electric fuel pump on the market, the Slimline Boxxer Fuel Pump
http://www.slimlineproducts.com/onli...oxxer_pump.htm . I've been using one for several years now and it's still running strong. Internally it's the same type pump as the highly rated, manual Dave Brown Six Shooter but electric powered. The housing is machined from billet aluminum. And best of all, parts are available for rebuild so when it does finally have problems you can just rebuild it instead of buying a new pump.
It does cost a few dollars more but way less than all the cheap pumps I went through in the same amount of time that I've used this one.
