LS EFI Fuel Tank Kit for 1962-1965 Chevy II/Nova X-Body
If you are fitting an LS powerplant into a 1962 to 1965 Chevy II or Nova X Body chassis you need a fuel tank that aligns with original mounts while delivering consistent flow. This EFI Fuel Tank Kit features a fully submerged 400 LPH Walbro pump module that minimizes heat soak and reduces vapor lock ensuring steady supply from idle to redline during demanding driving. Manufactured from stamped steel to the exact contours of the underbody the tank maintains factory ride height and avoids interference with rear suspension or exhaust tubes. Every component from the tank straps to the filler neck hardware ships complete for no fuss installation and lasting reliability.
Direct Fit Integration for LS Swap on Chevy II X Body
The kit uses a direct fit approach to align with the original Chevy II mounting points on the 1962 to 1965 X Body undercarriage. By matching the factory tank contours and ride height specification it avoids any contact with rear suspension or exhaust tubing. This precision stamping translates to consistent clearance across all units so each install preserves chassis integrity without trimming or modifications. The filler neck and vent outlets follow the stock routing so hose runs meet the original frame path and maintain a secure fit. Installers save time as the fuel tank drops into place and secures under the body with standard straps and hardware.
Fully Submerged Walbro Pump Module for Vapor Lock Prevention
Placing the Walbro 400 LPH pump module completely below the minimum fuel level keeps the unit cooled by surrounding fuel and prevents heat soak that can lead to vapor lock. The short feed path from splined pickup to outlet port reduces pressure loss and sustains a stable flow when the engine demands more fuel. Lab tests show that this arrangement maintains consistent pressure output even under heavy acceleration or extended driving sessions. Cooling action and stable delivery protect internal pump components and extend service life by minimizing temperature spikes. Fuel system service also remains straightforward as the module sits inside the tank and is accessed through the sending unit hatch.
Comprehensive Kit Components for Streamlined Installation
Every element needed for an LS conversion is included in one package to simplify assembly and avoid parts sourcing issues. The kit ships with the pump module, sending unit, tank straps, filler neck, vent filter, gaskets and all mounting hardware. Each component is tested to meet the pressure demands of engines that exceed 550 hp. Pre sized gaskets and precision drilled ports ensure each seal and hose connection aligns correctly the first time. With no extra parts required installers can maintain project momentum and complete the fuel system fit in minimal time.
Stamped Steel Construction Backed by USA Quality Standards
The fuel tank shell is crafted from heavy gauge stamped steel with tight chamber tolerances that deliver uniform capacity and strength from unit to unit. Weld seams and stake points receive thorough inspection to resist fatigue in rigorous driving conditions and protect against leaks over time. Surface treatments safeguard against corrosion caused by road chemicals and moisture while preserving the original underbody contours. Manufactured and assembled in the United States the kit benefits from controlled process checks and rapid quality feedback. Builders rely on this domestic support for consistent part availability and responsive technical assistance.
