To lengthen the life of your fuel pump be sure to always add a quality ethanol/fuel stabilizer to every fill-up of gas to your tank. This will help prevent sludge and varnish build-up in the pump, fuel lines, and carburetor. Switching to an electric 1 - 4PSI fuel pump at high elevations (over 5000ft) will be required.
