Check out the Walbro 2401-1 model. I have blown one in 15 years. They are about $80....
Walbro Fuel Pump 2401-1
They seem to last for quite some time. Mine is the 5 psi model.
A pressurised fuel system is the way to go. There is an added fire risk but air never leaks in. Fuel leaks out evey now and again, but you see it, and fix it.
