Reply to "Electric fuel pumps"

I can tell you some of the pitfalls. Most electric pumps will have wiring problems that cause them to shut down, either in the pump itself ala every Jaguar ever built, or in the connections to power the pump. As far as Holley or Carter rotary pumps, don't EVER let them run dry! The tiny impeller wheel inside the pump is brazed or soldered together and the heating one gets when running dry will cause the impeller to disintegrate in time. And every such pump I ever ran was extremely noisy. If this is for a good reason- like fuel injection that requires a much higher pressure, I suggest an in-tank pump mounted on the fuel tank sender bracket. I have no experience with the new in-line high pressure pumps. If you have a '71-72 Pantera, I also suggest using the stock welded outlet on top as your fuel return and adding a '73-up fuel gauge sender that has a fuel-out line integral with the unit, and bolts in with zero changes. They're a bit pricey new so I fabricated such an outlet to my early fuel sender, in an article in the PI magazine of Winter '99. Having some sort of fuel plumbing hanging from your drain plug on a low, fast car like a Pantera is not only in-elegant, its a disaster-in-the-making from rocks & road debris IMHO.
