Your fire-breathing 1000 HP monster show car needs a huge fuel pump to feed it, right? Yes and no! If the only racing it sees is the occasional burnout leaving the drive-through, your 100 GPH fuel pump may actually be working too hard trying to meet the low demand. The pump could even cavitate and vapor lock at idle or during part-throttle cruising. Constantly recirculating the excess fuel back to the tank can aerate, heat, and oxidize the fuel, causing problems elsewhere in the system. This trick controller from Aeromotive may be the answer!

Specifcally recommended for street-driven cars running large fuel pumps like the Aeromotive A1000 150 GPH Fuel Pump, this controller pulses the input voltage when engine RPM -- and fuel demand -- are low. As the revs rise, so does the pulse rate, until the pump is running at 100% duty cycle. The 40 amp output even eliminates the need for a fuel pump relay.

Note that this controller does not change the input voltage to the pump. Varying input voltage can damage some electric motors, and is ineffective on piston-type pumps. The pulsed 12 volt signal from this controller works with virtually any 12 volt pump.

The controller is pre-set to run the pump at full speed above 2500 RPM on V8 engines (3300 on 6-cyl and 5000 on 4-cyl). Changing the set point is as easy as revving the engine and pressing a button. An optional manual override switch (included in the kit) can also be used to run the pump at full speed whenever you want. Made in the USA.

Note 1: Cars with distributorless ignition systems will require the addition of a tachometer output adapter (such as the Auto Meter DIS Tach Adapter, Part No. AM9117), sold separately.
Note 2: Cars with forced induction running an electronic Fuel Management Unit will require additional tuning to help the FMU deal with the changing fuel pressure.
