Show original supplier description

The Lingenfelter Gen 3 Big Bore High Pressure Fuel Pump represents a significant redesign from Lingenfelter Performance Engineering, building on the success of their Gen 2 pump. This advanced fuel pump features a reconfigured LT4 fuel pump architecture enhanced with a proprietary spring configuration. Lingenfelter's engineered design further improves durability and fuel flow capabilities, addressing the limitations of factory fueling systems as power demands increase. It is built to meet these higher demands without compromising drivability or long-term durability. The Gen 3 Big Bore Fuel Pump is compatible with a wide range of GM Gen V engines, including E85 conversions. Specific applications include the LT4, LT1, LT2, L86, L83, and LV3 engines. It fits various models such as the C7 Corvette (LT1, Z06 LT4), Camaro SS (LT1), CTS-V (LT4), ZL1 (LT4), Silverado/Sierra (LV3, L83, L86), Suburban/Tahoe/Yukon/Escalade (L83, L86), C8 Corvette (LT2), CT5-V Blackwing (LT4), and various GM SUVs (L86, L87 platforms).
