The Aeromotive FPSC Advantage
Bottom line: You need to put enough fuel through the rail to feed the engine at a given load with enough leftover to keep the return line flowing and the pressure stable. Any flow over and above this is not absolutely required at that specific moment in time, but when you factor in the complexity of anticipating what the driver will do with his foot, it is wise not to slow the pump too much or one risks a dangerous lean condition. By utilizing a conservative but effective strategy that is user configurable with respect to base pump voltage followed by a progressive increase in duty cycle to a user-determined, high-rpm threshold, the new Aeromotive FPSC allows priority engine fueling with nominal fuel recycling. All the while, the pulse modulation strategy is totally friendly to the electric motor with the net effect of both extending fuel pump service life and further quieting pump operation.

We asked Clow his thoughts of the drawbacks of whether not using correct wiring or power to a fuel pump will affect the car's performance just as much as using a small inefficient pump. He said that was a pertinent question with respect to overall fuel system execution and that ultimately the system and its components are only as good as the installation. Failure to properly plumb and wire an Aeromotive high-performance fuel system is responsible for 98 percent of the difficulty people experience after the fact. This is simply critical and it's a crime, not to mention expensive, when the key details like proper wiring are allowed to render an otherwise capable fuel system unable to perform as advertised.
