1955-56 Chevy 150/210/Bel Air/Delray EFI Fuel Tank 400 LPH Pump for LS and LT
Placing a modern LS or LT powerplant into a classic 1955 through 1956 Chevy 150, 210, Bel Air or Delray body requires a fuel system that stands firm under sudden throttle inputs, and the 1955 through 1956 Chevy EFI Fuel Tank Kit 400 LPH Pump was purpose built to maintain precise flow without risk of starvation. Integrating a 400 LPH Walbro pump into a housing that mirrors original openings and strap mounting points eliminates the need for metal work or filler neck alterations. Manufactured in the USA from corrosion resistant materials, this assembly supports ethanol blends up to E85 and reliable service beyond 550 horsepower without leaks or pressure dips. Preassembled fuel line and electrical fittings align with factory holes so installation flows quickly for seasoned mechanics and ambitious hobbyists tackling LS and LT swaps.
Precision Fitment for 1955 to 1956 Chevy 150 210 Bel Air and Delray
The tank kit replicates original body curves and mounting points of 1955 to 1956 Chevy 150, 210, Bel Air and Delray models, matching strap locations and filler neck orientation to preserve ground clearance and classic silhouette. The sending unit housing aligns exactly with stock openings, ensuring a secure seal that prevents leaks even under heavy acceleration or rough terrain. Maintaining the factory underbody profile eliminates the need for trimming sheet metal or modifying the filler neck, streamlining the installation process. As a result, installers avoid custom fabrication or adapter plates, allowing the module to drop into place with first fit accuracy. This authentic fitment reduces installation time and preserves the integrity of the classic chassis. Owners benefit from a seamless integration of modern EFI components without altering the original design.
High Volume 400 LPH Walbro Pump Ensuring Stable Fuel Delivery
At the heart of the kit is a 400 liter per hour Walbro electric pump engineered to support engines exceeding 550 horsepower and to handle ethanol blends up to E85 without sacrificing pressure. An integrated pressure regulator and robust motor design maintain consistent fuel flow from idle through wide open throttle, preventing lean conditions or knock during rapid throttle transitions. The pump's high performance capability delivers smooth throttle response and reliable fuel mapping across various driving scenarios, from steady cruise to full boost runs. Both naturally aspirated and forced induction LS and LT engines gain a stable fuel supply foundation that enhances tuning precision and reduces power dips. This level of flow capacity is essential in performance applications where any loss of pressure can affect engine safety and driveability.
USA Made Corrosion Resistant Construction for E85 Compatibility
Constructed entirely in the USA, the fuel tank module uses corrosion resistant materials and coatings that meet rigorous salt spray standards, protecting metal components against moisture, road chemicals and modern fuel additives. Plastic parts are selected for thermal stability and chemical resistance, ensuring gaskets and seals remain intact under elevated temperatures and alcohol based fuel blends. This attention to material quality extends service life, reduces maintenance intervals and prevents the common issues of rust and seal failure over extended use. Whether deployed in a daily driver or a competition rig, the assembly stands up to harsh environments, delivering dependable, leak free performance season after season. Domestic manufacturing also ensures tight quality control and consistency across every unit.
Modular Assembly Streamlines LS and LT Engine Integration
The all inclusive kit arrives as a complete assembly, combining the pump, sending unit, vent filter, filler neck, gaskets, tank straps and mounting hardware into a single module ready for install. Each fuel line fitting and electrical connector is preassembled and routed, guiding installers through a logical sequence and reducing the risk of misrouting or missing parts. Alignment tabs and factory hole references allow the unit to seat perfectly in tight engine bays or beneath the chassis without the need for a lift or trial fittings. By streamlining part sourcing and eliminating guesswork, this design transforms a multi step swap into a streamlined project, cutting installation hours and minimizing frustration. Both professional shops and passionate hobbyists gain confidence that no component will be overlooked and that the kit will fit as intended.
