1964-1967 Chevy Chevelle EFI Fuel Tank with 400 LPH Pump for LS and LT Swaps
Swapping an LS or LT engine into a 1964 to 1967 Chevelle demands a fuel system that tucks neatly under the rear apron while delivering stable pressure to modern engines. This EFI fuel tank kit drops into the original mounting points without cutting frame rails or trimming straps, preserving underbody clearance and classic proportions. It incorporates a Walbro pump rated at 400 liters per hour alongside a calibrated sending unit for precise gauge readings through aggressive cornering and sustained high rpm runs. All necessary hardware including straps, gaskets and wiring pigtails comes in the box so installers stay focused on fitment rather than chasing extra parts.
Factory Alignment with Original Mounting Points
The fuel tank kit arrives shaped to match the 1964 to 1967 Chevelle frame rail spacing and strap locations, allowing it to drop into place without modification. By replicating the stock filler neck geometry, the system maintains factory hose routing and preserves underbody clearance under the rear apron. Installers benefit from a design that eliminates cutting or welding, reducing setup time and potential errors. This approach safeguards the car's classic proportions while providing a modern fuel delivery solution.
Submerged 400 LPH Walbro Pump Performance
At the core of the kit is a 400 liter per hour Walbro pump installed fully submerged within the metal shell, a configuration that resists heat soak and sustains consistent pressure during extended high load operation. This reliable volume capacity supports engines making more than 550 horsepower, preventing lean conditions that can lead to hesitation at high rpm. The pump module removes as one unit for simplified maintenance without dropping the entire tank.
Precision Fuel Level Sending Mechanism
The precision sending unit is calibrated to the internal shape of the tank, delivering accurate fuel level feedback across the full range of travel. Its low friction float arm moves freely even under cornering forces or steep inclines, avoiding false empty readings that could strand a driver. By reporting volume to within a fraction of a liter, the system protects the pump from running dry and helps drivers plan refueling stops with confidence on long drives.
Complete Fuel System Kit for Streamlined Assembly
This all inclusive package contains the tank shell, pump module, sending unit, tank straps, filler neck, vent filter, molded gaskets and all required hardware, eliminating the need to chase additional parts. Cut to fit seals ensure a leak free joint at the flange and spud, while the vent filter blocks debris from entering the reservoir. With every component on hand, installers can focus on fitment and finish, achieving a clean, reliable conversion.
