I have a 57 and just installed the electric fuel pump, it is rated 2.5 - 4 of pressure, my stock put out 4. So it is good for my Holley without a regulator. I plan on using it intermittently after she sits too long to prime the engines pump, lines and carb. I mounted it midway against the frame away from engine heat, there was a fitting joining the lines near a crossmember protecting the pump. I used all new metal lines, up to the engines pump (glad I did too, found a badly smashed section of fuel line), added a toggle switch under the dash so no one sees it.
