The Walbro 420 LPH High Flow In-Tank Fuel Pump (PN:GST450) flows 420 lph (111 gph) at 3 Bar and is capable of supporting up to 750 HP under standard operating conditions. Please see the graphs below for more information.

This fuel pump is designed for in-tank mounting for use with gasoline and features a compact stepped 39/50mm diameter body that fits most applications.

The innovative design features a single impeller with two parallel rows of turbine blades. The blades feed two high-pressure pumping channels, as opposed to a conventional single-stage pump that uses an impeller with a single row of blades at its outer edge. This innovative design results in improved hot fuel flow, as well as minimal noise and current use, resulting in efficiency that’s 20% higher than conventional pumps.
