255 LPH EFI Fuel Pump Module 63-67 Corvette

The 255 LPH EFI Fuel Pump Module 63-67 Corvette by Holley is an essential upgrade for classic Corvette enthusiasts transitioning from carbureted to fuel-injected systems. This module addresses a critical challenge: original fuel systems on first and second-generation Corvettes were not designed to supply the precise, consistent fuel delivery that modern EFI engines demand.

At 255 liters per hour (LPH), this EFI fuel pump module provides ample flow for both stock and modified small-block Chevy engines commonly installed in 1963–1967 Corvettes. The module integrates the pump, regulator, and necessary fittings into one compact assembly, ensuring proper fuel pressure calibration for your EFI system. Holley's engineering focuses on consistent delivery across RPM ranges and load conditions—critical for cold starts, smooth idle quality, and reliable wide-open throttle performance.

This module is ideal for restorers and hot rodders running Holley EFI systems, LS conversions, or other fuel-injected applications. The sealed design protects internal components from contamination while the modular construction allows for straightforward installation into the existing fuel tank cavity, although some modifications may be necessary.
