Walbro 255 LPH Internal Fuel Pump

APPLICATION: All Gen 3 and Gen 4 LS/Vortec engine swaps with an EFI-rated fuel tank.

The Walbro 255 LPH in-tank fuel pump supports up to 630HP and is QS9000 certified. Universal in-tank design, ideal for replacement, racing, or performance applications where higher fuel pressure/volume is needed. Includes wiring and pickup filter.

Internal fuel pumps are mounted inside the fuel tank, providing quieter operation and better cooling, while external fuel pumps are mounted outside the tank for easier access and maintenance. The Walbro 255 LPH pump is designed to provide reliable fuel delivery for both naturally aspirated and boosted high-performance LS and LT engines.

Great for conversions that already use an internal pump, like GM C/K trucks. If your vehicle was previously carbureted, you'll need an EFI-rated fuel tank and sending unit to run this pump.

Pairs well with our ACC-1028 Corvette Fuel Filter/Pressure Regulator.
