140 Gph Comp Fuel Pump

The 140 Gph Comp Fuel Pump by MALLORY is engineered for performance-oriented builders and mechanics who demand reliable fuel delivery in modified and high-output engines. This mechanical fuel pump excels in naturally aspirated builds, carbureted setups, and classic hot rods where consistent pressure and volume are non-negotiable. Whether you're restoring a vintage muscle car or tuning a street engine, the 140 Gph capacity provides the gallons-per-hour flow rate necessary to support sustained RPM and load without starving your carburetor or fuel injection system.

MALLORY's compensator design automatically adjusts fuel delivery based on engine demand, maintaining stable pressure across idle, cruise, and peak acceleration phases. This intelligent compensation prevents fuel flooding at high RPM and reduces vapor lock risk during extended high-heat operation—a critical advantage in tight engine bays and summer driving. The pump's mechanical actuation from the engine's camshaft lobe ensures zero electrical dependency, delivering the 140-gallon-per-hour output through a robust, cast-iron or aluminum housing designed to withstand decades of reliable service with minimal maintenance.

This pump suits small-block and big-block applications across Chevrolet, Ford, Mopar, and other platforms that use mechanical fuel pump mounts on the engine block. Installation requires verification of mounting pad compatibility and fuel line routing to avoid heat-related degradation near exhaust manifolds. The compact 6.6 x 3.9 x 9.9-inch envelope fits most traditional engine compartments, while its 4.85-pound weight contributes minimal parasitic load to your overall drivetrain.
