Sometimes, two pumps are better than one.

A suspicion that has long been speculated has officially been confirmed; that indeed, the new Fuelab EFPR (electronic fuel pressure regulator) can in fact operate two Prodigy Fuel Pumps simultaneously. In the picture shown, this “Frankenstein” mess has two Prodigy fuel pumps in parallel running through the new Fuelab EFPR.

With flow rates exceeding 325 GPH (over 2000 lbs per hour) the system remains calm. With low current draw (11.5 Amps) at zero flow rate or simulated idle, this system can run continuously for street use. Because of the unique patented design, flow rate through the regulator still remains low, so low in fact that the system operates with just a 3/8” return line! The test was conducted using a 42402-c and a 41403-c fuel pump to monitor capability and performance. The new 52901 regulator also has a zero to five volt output, to data log actual pump capacity as well as give a safety indicator. The system was operated for 45 minutes to examine heat build-up. Next step for this set-up: Get it on a live vehicle.
