Walbro 500-525 High-Performance 525 LPH In-Tank Fuel Pump E85 Compatible

The Walbro 500-525 (also known as the F90000285 or Hellcat pump) is a high-performance in-tank fuel pump featuring innovative DCSS (Dual Channel Single Stage) 39/50 turbine technology. This ultra-high-flow fuel pump delivers 525 liters per hour (470 LPH at 40 PSI), making it capable of supporting engines producing 700+ horsepower with forced induction and up to 900+ horsepower in naturally aspirated applications at 60 PSI.

Key Features:

• Flow rate of 470 LPH at 40 PSI (120+ gallons per hour) with 13.5V test voltage
• Compatible with gasoline, race gas, and E85/flex fuel applications
• Innovative dual turbine blade design on a single impeller for maximum pressure and superior fuel flow
• Internal check valve prevents fuel system pressure bleed-down and extended cranking at start-up
• High-pressure relief setting supports supercharger and turbo applications
• Remarkably quiet operation with 20% efficiency improvement over conventional pumps
• 39mm main housing diameter with 50mm lower housing (39/50 designation)
• Universal fitment - flush mountable to existing fuel hanger with installation kit

This TI Automotive engineered pump features award-winning OE technology originally designed for the Dodge Hellcat. The turbine-style pump head uses two parallel rows of turbine blades that pressurize fuel axially without forcing direction changes, resulting in tremendous flow rates across various rail pressures. All pumping components have been validated to OEM specifications for approved use in E85 and flex fuel applications. Professional installation recommended with upgraded wiring (14 gauge or larger), fuel pressure regulator, and appropriate fuel lines.
