Adapting an LS engine to a 1966-1967 Chevy II or Nova requires unwavering fuel delivery and this EFI tank kit with a 255 LPH pump is engineered to maintain the flow under demanding conditions. Built to fit the original X Body tank shell, it uses precision gaskets and hardware that secure installation without altering underbody ground clearance.

Across both daily commuting and spirited driving the kit sustains fuel pressure to prevent starvation and support consistent throttle response.
Consistent EFI Delivery with 255 LPH Walbro Pump
The heart of this fuel tank kit is the 255 LPH Walbro pump rated for LS engines up to 550 horsepower. By locating the pump inside the tank, it benefits from constant fuel cooling and reduced noise while maintaining stable pressure under rapid throttle changes. This steady supply prevents starvation during hard acceleration and supports precise injector operation for clean combustion. Quiet operation and proven durability make it a reliable choice for both commuter drives and spirited road use.
Precision Fitment for 1966 1967 Chevy II X Body Frames
Every contour of the kit is shaped to follow the original Chevy II and Nova X Body tank shell without requiring frame or floor modifications. Mounting points align exactly with factory holes, preserving under body clearance and preventing interference with suspension or exhaust components. Precision cut gaskets and hardware create a tight seal against leaks while retaining the stock silhouette beneath the car. This vehicle specific approach ensures that installers can complete the job without altering period correct lines.
Integrated Fuel Management Components for Reliable Operation
This complete kit combines the pump module, calibrated sending unit, vent filter, tank straps, filler neck, gaskets and mounting hardware into one package. The sending unit is engineered to match factory gauge curves, offering accurate fuel level readings for peace of mind. A high quality vent filter keeps dirt and moisture out of the system, prolonging the life of pumps and lines. Each component works together to simplify installation steps and reduce the chance of leaks or misalignment.
Blending Classic Styling with Modern EFI Performance
While preserving the tank's original appearance, this kit adds the reliability of modern electronic fuel injection. The optimized fuel delivery improves throttle response and fuel economy under all driving conditions, from stop and go traffic to spirited back road runs. By marrying vintage underbody aesthetics with up to date EFI technology, drivers enjoy the look of a period correct installation along with the peace of mind that comes from consistent fuel pressure. The result is a powertrain solution that honors classic design without compromising performance.
