Electronic Fuel Pressure Regulators (EFI)
FUELAB® electronic fuel pressure regulators work directly with our Prodigy line of fuel pumps to reduce heat build up and vapor lock conditions. The 529 series fuel pressure regulator sends a signal to the Prodigy pump to control return line flow rate. With the FUELAB® demand based system, true pump control is finally achievable and easy to install! Super fast response time, independent system, no calibration! Now compatible with our new 617xx Series FST and 72002 Fuel Pump Controller!
