Gen-V LT4 High Pressure Fuel Pump

The Gen-V LT4 High Pressure Fuel Pump is a critical performance component for enthusiasts and professional mechanics building high-output GM Gen V engines. Designed to meet the increased fueling requirements of direct injection systems, this pump ensures that your engine receives the precise volume of fuel needed during high-load operation. It is an ideal solution for those upgrading an LT1 engine or replacing a factory unit to maintain peak performance levels. This pump provides the necessary overhead for power adders and aggressive tuning profiles.

Technically, this unit operates as a mechanical fuel pump driven by the engine's camshaft, providing the consistent pressure required for modern direct injection injectors. The Gen-V LT4 High Pressure Fuel Pump features a stock quick-disconnect inlet for easy installation and a 14 mm x 1.50 male outlet for a secure, high-pressure seal. Its inline design is engineered for durability, utilizing high-grade materials to withstand the thermal stress of high-performance environments. By maintaining superior flow rates, it prevents the lean conditions that can lead to engine damage under boost.

This component is highly recommended for drivers who plan to buy performance upgrades such as superchargers or upgraded camshafts for their LT-series vehicles. Compatibility is centered on the GM Gen V platform, making it a staple for Corvette, Camaro, and truck owners seeking factory-level reliability with aftermarket power potential. Before finalizing your build specifications, ensure that your fuel system can support your horsepower goals with this high-pressure solution. Professional installation is encouraged to ensure the fuel system is properly primed and sealed for long-term operation.
