Walbro 255lph GSS342 Fuel Pump (1 Pump)
**Note: This is a return style pump. Do not use this pump in a returnless style fuel system as it can severely shorten the life of the pump. Please look at the DivisionX Stryker 340 or Aeromotive Stealth 340 as alternatives that can be used in return or returnless style fuel systems.
The Walbro high output in-tank electric fuel GSS342 pumps have flow ratings of 255 liters of fuel per hour. These particular pumps flow significantly more fuel at higher pressure. For example, at 80 PSI the standard 255 lph pump will flow around 132 liters (35 gallons) per hour. At that same 80 PSI the equivalent HP (high pressure) fuel pump will flow over 210 liters (50 gallons) per hour.
Walbro in-tank electric fuel pumps utilize a proven gerotor design. The outside dimensions, however, are compact enough to fit existing hanger assemblies, without modification.
