1957 Chevy 150/210/Bel Air/Delray LS EFI Fuel Tank Kit with 255 LPH Pump
When installing an LS system in a 1957 Chevy 150, 210, Bel Air or Delray the tight floor pan demands a precise solution and the EFI fuel tank kit with its 255 LPH Walbro pump seats directly into factory mounts. This EFI fuel tank kit maintains original underbody geometry so install skips any cutting or welding while supplying consistent pressure for engines up to 550 hp. A calibrated float sending unit ensures accurate level readings during cornering for confident trip planning. Original style filler neck and hardware complete a plug and play assembly that replaces complex custom fuel system mods.
Precision Alignment for 1957 Chevy Floor Pan Geometry
The tank body is CNC-formed to follow the exact curves of the 1957 Chevy 150, 210, Bel Air and Delray floor pan, ensuring the flange seats perfectly against factory mounting points. By matching the original underbody profile, installers can retain the stock frame rails and mounting brackets without any cutting or welding, preserving the vehicle's structural integrity. A continuous seal between the tank flange and body mounts keeps contaminants out and fuel vapors contained, reducing risk of leakage over years of use. Because the assembly slips directly into place, build time is significantly reduced and the need for custom brackets or shims is eliminated. In essence, this precision alignment honors the classic chassis geometry while integrating modern EFI hardware seamlessly.
Consistent Fuel Delivery with High-Flow 255 LPH Pump
The heart of this fuel system upgrade is a 255 LPH Walbro pump chosen for its ability to sustain engine outputs up to 550 horsepower under sustained load. Internal baffling inside the module ensures that the inlet remains submerged even during hard cornering or rapid acceleration, preventing air ingestion and momentary fuel starvation. This design maintains a stable pressure curve that supports aggressive throttle transitions and high rpm operation without lean spikes. The pump's compact footprint fits entirely within the tank, keeping the exterior lines free of bulky external units and safeguarding against road debris. Service intervals are extended thanks to durable internal components proven in demanding racing and street applications. As a result, engine calibration remains predictable and performance smooth, drive after drive.
Accurate Fuel Level Monitoring in Dynamic Conditions
The integrated sending unit employs a guided float arm that compensates for fuel slosh when navigating turns or uneven roads, delivering stable level readings to the dash gauge. Precision pivot points and calibrated arm geometry eliminate the erratic needle jumps common in retrofitted tanks, giving drivers a true indication of remaining fuel at all times. This consistency helps avoid unexpected low-fuel situations on long outings or spirited drives, improving trip planning and peace of mind. Technicians also benefit from reliable data when tuning fuel trims or diagnosing consumption patterns, as the unit tolerates vibration and shock without drifting out of calibration. By aligning modern sensing technology with the classic Chevrolet fuel system, this kit turns a common retrofit challenge into a straightforward solution.
All-in-One Kit for Streamlined EFI Installation
Every component needed for a complete EFI upgrade is included and engineered to work together right out of the box. The assembly comprises the pump module with integrated filter, precision sending unit, original-style filler neck, vent filter, tank straps, molded gaskets and all necessary hardware. Each part is metal-to-metal tested for fit and the instructions specify torque values and clamp locations to guarantee leak-free performance. Pre-formed straps hook directly to factory frame points and the filler neck aligns with the stock body opening, eliminating guesswork and fabrication. By consolidating this array of components into a single package, the kit minimizes sourcing delays, reduces compatibility conflicts and delivers a truly turnkey solution for classic Chevy EFI conversions.
