ESTIMATED SHIP DATE: END OF FEBRUARY 2026
Lingenfelter Performance Engineering is now accepting pre-orders for our new Gen 3 Big Bore High Pressure Fuel Pump.
After nine years of setting the standard with our Gen 2 big Bore fuel Pump, Lingenfelter went back to the drawing board to completely redesign the all-new Gen 3 Big Bore Fuel Pump in collaboration with Stanadyne. This pump is designed to support higher horsepower Gen V applications with increased fuel capacity, consistent performance, and OEM-level reliability.
The Lingenfelter Gen 3 Big Bore Fuel Pump utilizes a reconfigured LT4 fuel pump architecture with a proprietary spring configuration, combined with an all-new Lingenfelter-engineered design to improve durability and fuel flow capability.
As power demands increase, factory fueling becomes a limiting factor. This new big bore pump is built to address that challenge without compromising drivability or durability.
