1968-1969 Chevy Chevelle A-Body EFI Fuel Tank Kit with 255 LPH Pump for LS Swap
Tackling an LS swap in your 1968 to 1969 Chevy Chevelle A body often hinges on solving tight exhaust and tire clearance issues while maintaining a reliable fuel supply. This kit features a notched tank design for frame rail and exhaust clearance, paired with a high flow 255 LPH pump that supports up to 550 horsepower builds. Installation uses factory mounting points and stock fuel lines to minimize downtime, while the rugged steel construction resists corrosion and keeps fuel delivery consistent under vigorous street or track use.
Precision Notched Fuel Tank Geometry for Chevelle Frame Clearance
The notched contour of the tank is engineered to provide unobstructed space for exhaust runs and wheel rotation after an LS swap. By shaping the lower rail area with strategic cutouts, the tank avoids interference with frame rails and rear tires even under extreme suspension travel. This feature preserves chassis geometry while allowing modern header systems to tuck neatly. It also reduces the risk of tank deformation or abrasion during spirited driving, ensuring consistent clearance and reliability.
Walbro 255 LPH Pump Module Ensuring Consistent Fuel Delivery
At the heart of this system is a Walbro 255 LPH pump that supports up to 550 horsepower engine outputs. Its high capacity rotor assembly maintains stable pressure during wide open throttle events, preventing lean conditions and promoting pump longevity. The in tank module design isolates the unit from engine heat and road debris, reducing noise and micro vapor lock. In practical terms this means smooth running at any RPM, from idle traffic creep to hard launch off the line.
Durable Construction and Complete Component Integration
The fuel tank is fabricated from heavy gauge steel with a corrosion resistant finish to withstand ethanol blended fuels and road moisture. Included are all critical parts for a turn key upgrade: sending unit, straps, filler neck, vent filter, gaskets, and mounting hardware. This complete assembly approach eliminates the need to source compatible aftermarket bits, delivering a robust platform designed for both street cruising and track duty. Every component works in concert to provide dependable operation under demanding conditions.
Direct Fit Installation with Factory Points and Stock Lines
Designed specifically for the 1968 to 1969 Chevelle A body, this kit reuses original mounting brackets and standard fuel hoses to simplify the swap. By matching factory tank contours and inlet locations, the system installs without major frame modifications or custom line bending. This reduces installation time and cost while preserving chassis integrity. In most cases you can secure the tank, route existing hoses, and fire up your engine in a single afternoon.
