<VV> Electric fuel pump

On my 1963 Rampside, I have a Carter electric pump (w/ fuel filter just before pump inlet) mounted on rear panel frame rail directly center/behind fuel tank mounted in a coil bracket attatched to the body with 2 rubber mounts. Fuel "siphons" from the tank to the pump. This pump is both quiet and vibration free. At the engine (95 HP mostly stock) I am using the original pump (as a dummy) without pushrod as a fuel adaptor only so that I can still use the OE fuel pipes and not be concerned with belt coming off and breaking a line.It works well for me.

>A poorly installed electric fuel pump is much worse than a mechanical pump. I once bought a 66 110 hp Corvair?that had an electric fuel pump installed on the lower shroud by the oil cooler. The 'mechanic' that installed it made his installation easy by running hose between the body fuel line and the inlet of the pump. He routed the hose right on top of the head shroud. It was a hot August day in Iowa, and you can probably guess the rest of the story...I made it about 10 miles before it acted like I was out of fuel. We pulled it home and put the correct line on it and a mechanical pump and it worked fine. What was happening is that the hose was collapsing from being so hot and on the suction side of the pump.
