I use electric pumps for glow, gas and turbine fuels. The electric pump that I have found to work the best out of all of them, is the Sig fuel pump. It has an enclosed case for elimiation of spark for gas/jet fuels. I have one pump that has pump gallons of fuel in the past 2.5 years of owner ship. Never a problem. We fly weekly here in Florida, so it has seen a LOT of use filling a 50 oz tanks. They are more expensive, but last a lot longer. They have restrictors for the smaller fuel tanks to cut the flow down.
