1964-1967 Chevy Chevelle EFI Fuel Tank Kit with 255 LPH Pump for LS Swaps
Swapping in an LS engine for a 1964-1967 Chevelle pushes factory fuel systems past their limits, and the 1964-1967 Chevelle EFI Fuel Tank Kit - 255 LPH Pump provides a direct fit in tank conversion that drops into original mounting points with no fabrication. The submerged Walbro module runs cooled by surrounding fuel, delivering steady fuel pressure under acceleration while reducing vapor lock risk. Complete hardware including straps, gaskets and a vent filter simplifies assembly while preserving original tank bay shape. A calibrated sending unit mirrors the factory resistance curve for accurate gauge readings, keeping you informed of fuel levels during long drives or track runs.
Submerged Walbro Pump Delivers Stable Fuel Pressure
The Walbro module sits entirely inside the fuel tank, where it stays cooled by the surrounding liquid to prevent heat soak and vapor lock. Its 255 LPH capacity is engineered to meet the demands of engines producing up to 550 hp, ensuring uninterrupted flow under heavy throttle. By replacing only the internal components, this design maintains original routing and clearance beneath the car for a seamless installation. The submerged arrangement also prolongs pump life by reducing thermal stress on internal parts. The result is consistent delivery of fuel pressure whether you're cruising or accelerating hard on the road.
Direct Drop in Tank Retains Original Fuel Bay Structure
This EFI conversion package installs into the existing Chevelle fuel bay without cutting or welding, preserving the factory frame rails and sheet metal contours. Mounting points align exactly with the stock positions, letting installers reuse the original straps and body holes. The filler neck and vent filter slot into the stock openings, maintaining a clean appearance under the vehicle. By eliminating custom brackets or trimming, the solution speeds up installation and keeps the tank bay true to its classic look. End results are both structurally sound and visually faithful to the 1964 to 1967 Chevelle design.
Precision Fuel Sender Ensures Accurate Gauge Readings
The sending unit in this kit is calibrated to match the original resistance curve, delivering fuel level data that mirrors the factory gauge response. A corrosion resistant float arm and robust wiring harness maintain smooth electrical contact over years of use, preventing erratic or false empty warnings. With that linear output, drivers gain confidence in remaining range during long drives or spirited runs. This precise feedback avoids surprises at the pump and helps plan refueling stops with greater accuracy. It's a critical upgrade for any LS powered Chevelle where reliability is paramount.
Comprehensive Kit Components for Efficient Assembly
Every part needed for the EFI conversion is included, from the pump and internal module to tank straps, filler neck, vent filter, gaskets, and fastening hardware. Clear step by step instructions guide you through proper gasket placement and torque values to ensure a leak free seal. Builders save time by not hunting down compatible fittings, while achieving a professional quality outcome. The complete hardware package also reduces the risk of installation errors and costly callbacks. With this all inclusive kit, transforming your classic Chevelle to reliable fuel injection becomes a straightforward project.
Engineered for precise tank integration and reliable pressure delivery for your LS swap. To complete your upgrade with a Larger capacity fuel pump Kit at 400 LPH see our 1964-1967 Chevelle EFI Fuel Tank Kit - 400 LPH Pump.
