I really don't understand all the smack down on electric pumps. An electric pump is a MECHANICAL PUMP that uses a DC motor to drive it. All of your electricity is generated by machinery that use electric driven mechanical pumps for auxiliaries for example. Uhhhh they run 24/7. A Gerotor pump is pretty damn bullet proof. Thats why they are one of the most popular mud pumps in the oil drilling industry. If you think that a rubber pulsating bladder (ie automotive mechanical pump) is more robust than two high strength metal gears that don't even touch (Gerotor) then bless your hearts.

That said it ain't usually the electric pump's fault, be it Gerotor or RV, that it has problems; it is generally misapplied or specified for the application intended.

I had a 427 Vet that had a mechanical pump and would run out of gas above 4500 rpm. Guess what an electric pump solved that problem. I ran a Carter electric pump in 70's and never had a problem. You just cannot make me believe they are ANY less dependable than mechanical pumps.

And finally, I challenge any of you to show me a mechanical driven pump on any modern factory car.

Practice your bends on cheap steel and not aluminum stock. It will have similar modulus and strength properties of stainless steel. Not everyone is a natural plumber. The sand trick will indeed help but you sure don't want that ending up in your carb.
