EFI Fuel Tank Kit for LS Swaps in 1957 Chevy 150 210 Bel Air Delray
When fitting an LS injection system into a 1957 Chevy 150, 210, Bel Air or Delray, ensuring a reliable fuel source within the constraints of the factory floor pan is a key concern and the EFI Fuel Tank Kit solves it by slipping a 255 LPH pump into the stock mounting points for a straightforward swap. By preserving the original frame geometry the assembly installs without cutting or welding and replaces complex fuel system mods with a true drop in solution. The high flow pump maintains consistent delivery for engines up to 550 hp, preventing pressure drops during rapid throttle changes or sustained high rpm. A calibrated sending unit delivers precise level feedback on the dash through cornering or uneven terrain, helping drivers plan refueling stops with confidence.
Precision Fit for 1957 Chevy Floor Pan Geometry
The fuel tank in this EFI kit is shaped to mirror the contours of the original 1957 Chevy floor pan and frame rails, ensuring the assembly aligns precisely with factory mounting points. By preserving the stock geometry, installers avoid cutting or welding, cutting installation time and minimizing potential for error. This exact match maintains consistent contact between the tank flange and body mounts, promoting reliable sealing and reducing the risk of leaks over time. The result is a direct fit that retains the classic underbody appearance while accommodating modern injection hardware. Ultimately, builders benefit from a seamless integration that respects the vehicle’s original structure and foundation.
Stable Delivery with High-Flow 255 LPH Pump
At the heart of this tank kit sits a high-flow 255 LPH Walbro pump selected for its proven performance in demanding EFI applications. It maintains consistent fuel pressure under rapid throttle inputs and high engine speeds, supporting LS conversions up to 550 horsepower without lean conditions. This level of flow capacity prevents momentary starve events during aggressive acceleration or extended high rpm runs, ensuring reliable power delivery in spirited driving. The pump module is engineered for long service intervals, with internal baffling that minimizes air ingestion and maintains prime even when fuel levels drop. As a result, the engine calibration remains stable under all load scenarios, and drivers can push the powerplant with confidence.
Precision Fuel Level Sensing Under Dynamic Conditions
The integrated sending unit features a precision float mechanism designed to counteract fuel movement when cornering or on uneven terrain. By providing accurate real-time data to the dash gauge, it eliminates erratic readings that often plague classic tank retrofits. This consistency helps drivers plan refueling stops with confidence and avoids pinching the engine on remote drives. In addition, precise level feedback assists with EFI system diagnostics and tuning, allowing technicians to monitor fuel consumption trends without guesswork. The result is both a more predictable driving experience and a tool for maintaining optimal engine calibration.
Comprehensive Component Selection for Turnkey Installation
This kit delivers every element needed for a drop-in EFI upgrade, from the pump and module to the sending unit, filler neck, vent filter, tank straps, gaskets and hardware. Each component is engineered to work together, eliminating the need for aftermarket adapters or additional fabrication. Detailed instructions guide installers through each step, ensuring correct torque specs and clamp locations to prevent leaks. By streamlining the parts list into a single package, builders avoid sourcing delays and compatibility issues that can stall a project. The cohesive design and included fittings make this solution truly turnkey for classic Chevy fuel system upgrades.
