2nd Fuel Pump

Recommended Posts

You can if you use the function 'FP speed' on one of your aux outputs ,and use the designated output to ground a relay feeding that other pump. You can span it over injector dutycycle and RPM.

You CAN run both at the same time. It just depends on your system. One problem you MIGHT run into are 'regulator overrun' Thats when your pumps are pumping more fuel than your injectors use and what your regulator are able to bypass. Fuelpressure will then increase unnintencialy.
