Walbro GST400 390 LPH Fuel Pump
TI Automotive (Walbro) manufactures a complete line of fuel pumps, accessories, pump kits, and fuel modules for the high-performance aftermarket. Approximately two-thirds of the vehicles produced around the world feature TI Automotive’s products and technology. TI Automotive’s award-winning fuel delivery system technology is featured on some of the world’s highest performing production vehicles and supercars.
Walbro's 390 LPH High Flow In-Tank Fuel Pump is designed for high performance naturally aspirated and forced induction EFI vehicles. It delivers impeccable performance and high volumes of fuel flow.
The Walbro 390 LPH High Flow In-Tank Fuel Pump (PN:GST400) flows 390 lph (103 gph) at 3 Bar and is capable of supporting over 500 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.
