EFI Fuel Tank Kit for LS Swaps in 1957 Chevy 150/210/Bel Air/Delray
The 1957 Chevy EFI Fuel Tank Kit with 255 LPH pump overcomes tight floor pan constraints and complex routing when installing an LS powerplant in a 1957 Chevy 150, 210, Bel Air or Delray. By slipping directly into factory mounts it preserves the original underbody shape and eliminates the need for cutting or welding while ensuring precise fuel delivery for engines up to 550 hp. Its calibrated float sending unit and original style filler neck complete the plug and play package that delivers consistent pressure under hard cornering and simplifies installation on classic Chevrolet bodies. Detailed instructions and included hardware allow builders to focus on tuning rather than fabrication.
Seamless Floor Pan Integration for 1957 Chevy EFI Tank
The fuel tank body is CNC formed to match the exact contours of the 1957 Chevy 150, 210, Bel Air and Delray floor pan, enabling installers to reuse factory mounts without modifying frame rails or cutting metal. This precise fit preserves original underbody geometry and maintains structural integrity by seating flush against OEM mounting points. A continuous seal formed by molded gaskets prevents fuel vapors from escaping and shields against road debris intrusion. Slip-in alignment with existing fasteners means builders spend less time fabricating brackets and more time on tuning and finishing.
Reliable 255 LPH Pump Supporting Up To 550 HP
At the heart of the kit sits a 255 LPH Walbro pump engineered to deliver consistent pressure for engines producing up to 550 horsepower. Internal baffling in the module keeps the inlet fully submerged during tight cornering or sudden acceleration, eliminating air ingestion that causes fuel starvation. Its compact design fits entirely inside the tank, maintaining hidden lines and reducing exposure to external damage. Proven in race and street applications, this high capacity pump ensures stable fuel supply under sustained load and rapid throttle transitions.
Precision Float Sending Unit for Consistent Readings
The integrated sending unit features a guided float arm calibrated to counteract fuel slosh in dynamic driving scenarios, providing accurate level data to the dash gauge. Precision pivot points and carefully tuned geometry eliminate needle jumps that occur in retrofitted tanks, giving drivers real-time feedback on fuel reserves. This consistent output helps avoid unexpected low-fuel situations on long trips or spirited drives and assists technicians in tuning fuel trims with reliable consumption data. Robust construction tolerates vibration and shock without drifting out of calibration.
Complete EFI Kit Streamlining Fuel System Assembly
This all-in-one solution includes the in-tank fuel pump module, precision sending unit, original style filler neck, vent filter, molded gaskets, tank straps and all mounting hardware needed for installation. Each component is tested for fit and function, and the step-by-step instructions specify torque values and clamp locations to guarantee leak-free performance. Preformed straps attach directly to factory frame points while the filler neck aligns with the stock body opening for a truly plug and play installation. Consolidating these parts into a single package eliminates compatibility conflicts and sourcing delays for classic Chevy EFI conversions.
