LS EFI Fuel Tank Kit for 1955-1956 Chevy 150/210/Bel Air/Delray
When swapping an LS engine into a 1955 to 1956 Chevy 150, 210, Bel Air or Delray, consistent fuel pressure is essential for reliable performance. This EFI conversion solution integrates a 255 LPH pump module, sending unit, vent filter, filler neck, straps, gaskets and hardware within a sealed steel housing matched to factory rails. Compatible with LS and LT platforms supporting up to 550 hp, this design preserves factory ride height and underbody clearance by eliminating external feed lines. Placing the pump at the lowest point in the reservoir improves fuel density and helps prevent vapor lock during spirited driving. Precision stamped mounts and pre sized parts ensure a direct fit and reliable operation from idle through redline.
Overview
The 1955-56 Chevy EFI Fuel Tank Kit with a 255 LPH pump delivers a fully integrated in tank module designed for seamless conversion to electronic fuel injection. Offering support up to 550 horsepower, this assembly provides steady fuel volume where classic mechanical systems fall short. Its architecture allows consistent pressure under varying load conditions which translates to stronger throttle response and improved drivability. Every unit is manufactured in the USA to ensure quality control and long term durability on show car restorations or daily drivers that demand modern performance from vintage chassis components.
Performance Benefits
At the heart of this system lies the Walbro 255 LPH unit, which establishes a reliable flow rate optimized for street and track use. By maintaining stable pressure at high rpm and under boost, the kit eliminates fuel starvation during hard acceleration. Integrating the pump inside the tank reduces noise and exposure to heat so fuel remains cool for denser charge and cleaner combustion. The result is more consistent power delivery, reduced turbulence in lines, and a more predictable tuning window for aftermarket engine controls. End users will appreciate how the module's self contained design lowers installation complexity while boosting overall system integrity for high output LS or LT builds.
Installation and Fitment
This fuel tank kit is engineered to fit the 1955-56 Chevy LS and LT platforms without modification to frame rails. It mates directly with MuscleRods engine mounts, guaranteeing precise engine placement and accurate drivetrain angles essential for maintaining proper geometry and reducing stress on transmission mounts and u joints. The tank's contours follow the chassis profile for a snug installation, and the kit includes all fittings, hoses, gaskets, and a detailed instruction sheet to guide professional technicians or experienced home mechanics through a streamlined assembly process. Wiring harness connectors conform to OE style plugs for quick integration with existing EFI systems, while the pump's quick disconnect coupling simplifies service. This solution delivers a direct upgrade path for classic vehicles seeking modern fuel delivery reliability and peak throttle performance.
