Review on 💪 Carter P4594 In-Line Electric Fuel Pump: Maximize Engine Performance by Sean Davis

This pump works perfectly but does not match the specifications in the description. The pump delivered 7 psi static pressure when first installed, but after a day of use it was only delivering 4.5 psi static pressure. I installed this pump on my 330hp stock engine. 454ci. This engine should be using less than 30 gallons per hour when running at WOT. A free flow of 72 gallons per hour would be enough if the pump was actually delivering that much fuel. Fuel pressure fluctuates between 3 and 4 psi at idle and often drops to 2 psi at 2800 rpm. At higher RPM the pressure drops to 0 psi. This pump can handle smaller engines, but I wouldn't recommend it for anything in the 250+ horsepower range. Because of the low price, I might end up buying another one and running it at the same time. However, I probably would have chosen a different pump in the first place if I had known that this pump was not up to spec.
