1955-1956 Chevy 150/210/Bel Air/Delray EFI Fuel Tank Kit 400 LPH Pump for LS and LT
When fitting a modern LS or LT engine into a classic 1955-1956 Chevy 150, 210, Bel Air or Delray, maintaining stable fuel flow under sudden throttle transitions is critical. The 1955-1956 Chevy EFI Fuel Tank Kit with its 400 LPH Walbro pump solves this by combining a high capacity unit with factory style openings and strap mounts to drop in without modifying the sheet metal. Constructed in the USA from corrosion resistant materials, it supports ethanol blends up to E85 and sustained use beyond 550 horsepower while preserving the stock underbody profile. With preassembled lines and connectors aligned to factory holes, installers spend less time on fabrication and more time refining tuning.
Precision Body Integration for LS and LT Powerplants
The tank module follows the exact body contours and strap locations of 1955–56 Chevy 150, 210, Bel Air, and Delray models, aligning the filler neck and sending unit opening without any need for body modifications. By mirroring factory underbody clearances, it preserves the classic profile and maintains original ground clearance under the chassis. Precise alignment with stock mounting holes means the unit seats securely on the frame rails, eliminating the guesswork that often accompanies modern engine conversions. This level of fit accuracy reduces installation time and ensures that the new fuel system integrates seamlessly with the period sheet metal.
High Volume Fuel Delivery with a 400 LPH Walbro Pump
At the heart of this kit is a 400 LPH Walbro electric pump engineered to support supercharged and over 550 horsepower applications without fear of fuel starvation. An integrated pressure regulator and resilient motor design maintain stable flow from idle through wide open throttle, safeguarding against lean conditions and knock. Handling ethanol blends up to E85, the pump delivers consistent volume under varying temperature and fuel composition. This capability provides tuners with the fuel headroom needed for aggressive maps, eliminating dips in pressure that can compromise performance and reliability.
Corrosion Resistant Domestic Construction for Ethanol Blends
Every metal component in the tank assembly is treated with corrosion resistant coatings that meet stringent salt spray standards, protecting against moisture, road chemicals, and modern fuel additives. High grade plastics resist thermal breakdown and chemical attack, ensuring seals and gaskets remain leak free under elevated underhood temperatures and alcohol content. Domestic manufacturing allows for tight quality control of welds and material thickness, extending service life and reducing maintenance cycles. This robust build quality supports long term operation in daily drivers and competition rigs alike, delivering dependable performance season after season.
Modular Kit Design Streamlines Installation Process
The complete assembly arrives ready to install, combining the pump, sending unit, vent filter, filler neck, straps, gaskets, and hardware into one self contained module. Each fuel line and electrical connection is pre routed and fitted to factory hole locations, guiding installers through a logical sequence and reducing the chance of misrouted hoses or loose fittings. Alignment tabs and reference markers on the housing ensure a first fit alignment under the chassis without trial and error. By consolidating all critical components into a single unit, the kit turns what was once a multi step fabrication task into a straightforward installation for both professional shops and dedicated enthusiasts.
