The Holley 255 LPH Fuel Pump Replacement for Retrofit Fuel Tanks is a high-capacity electric in-tank pump engineered to supply fuel-injected and carbureted engines with consistent pressure and volume during aggressive driving. Rated at 255 liters per hour at 60 psi, this pump delivers the flow necessary for performance applications, engine conversions, and fuel system upgrades where OEM pumps fall short or are unavailable for custom tank installations.
Designed as a direct replacement for retrofit fuel tanks, the pump features a 1/4 inch NPT outlet connection for flexible fuel line integration into existing or new fuel systems. The 255 lph specification ensures adequate supply pressure for multi-point fuel injection systems and high-flow carburetor applications without starvation under full throttle. The in-tank design keeps the pump submerged in fuel for cooling and longevity, eliminating external pump mounting complexity. Holley's engineering ensures this replacement pump meets the electrical and mechanical specifications required for seamless drop-in installation in retrofit scenarios where fuel tank capacity or layout demands a non-OEM solution.
This pump serves builders, restorers, and performance enthusiasts upgrading fuel systems for street rods, classic car restorations, engine swaps, and custom fabrication projects. It is the correct choice when original equipment pumps are incompatible with modified or aftermarket fuel tanks, or when increased fuel delivery is needed for carbureted performance builds. The gasoline-rated construction makes it suitable for conventional fuel applications across a broad range of displacement and induction configurations.
Holley's 255 lph pump sits in the mid-to-high capacity range for in-tank electric pumps, making it versatile for street performance and mild competition use. At 0.85 lbs, it is lightweight and compact enough to fit retrofit tanks with space constraints, simplifying installation in vehicles where factory tank removal or modification is part of the fuel system upgrade process.
