Walbro GSL392 255LPH High Pressure Inline Fuel Pump are extremely popular upgrades to vehicles with engine and performance modifications, supporting over 600 horse power in well tuned N/A applications. These fuel pumps feature a lightweight, compact design for durability and simplicity. With a base fuel pressure of 45psi the Walbro 255 is able to deliver over 65lbs an hour of fuel. A good rule of thumb for standard pump fuel is 10hp per pound of fuel. You must run a pre-filter as well, here is what I like to use. 

Engine Output with Pump Fuel:

  • Naturally Aspirated - 500hp
  • Supercharged - 400hp+
  • Turbocharged - 400hp+

Engine Output with E85 Fuel:

  • Naturally Aspirated - 400hp+
  • Supercharged - 300hp+
  • Turbocharged - 300hp+

  • Outside Diameter: 1.70"
