1964-1967 Chevy Chevelle EFI Fuel Tank Kit with 400 LPH Pump for LS/LT Swaps
Installing LS or LT power in a 1964 to 1967 Chevelle requires a fuel delivery system that fits the chassis and supports modern output levels. This EFI Fuel Tank Kit with its 400 LPH pump drops into the stock mount points, preserving frame rails and underbody clearance without extra brackets or cuts. By pairing an all-American tank shell with a Walbro 400 LPH pump and precision sending unit, gauge readings stay accurate even under cornering forces and sustained high demand. Installers find wiring, straps and gaskets included so work stays focused on fitment rather than sourcing components.
Factory Mount Alignment for Unaltered Chassis
This fuel tank kit is engineered to drop directly into the original mounting points of a 1964 to 1967 Chevelle chassis, eliminating the need for cutting or fabrication. By matching the frame rail spacing and strap locations exactly, the tank preserves underbody clearance and the truck lines remain pristine. The filler neck orientation duplicates factory geometry, so routing existing fuel lines and filler hoses is seamless. An all American shell mirrors the contours of the stock reservoir and ensures the tank integrates invisibly beneath the rear apron. Installers will find the fitment so precise that trial adjustments are virtually eliminated, reducing install time and minimizing the risk of fastener misalignment. This approach safeguards the vehicle's classic appearance while updating fuel delivery capability.
Integrated 400 LPH Walbro Pump Ensures Consistent Delivery
At the heart of this kit is a Walbro pump rated at 400 liters per hour, chosen for its ability to sustain the flow demands of engines producing upwards of 550 horsepower. Because it operates fully submerged, the unit resists heat soak and maintains stable pressure during extended high load runs. Drivers experience crisp throttle response even under hard acceleration or track laps, as the pump continues to deliver a steady volume of fuel. This reliable flow capacity prevents fuel starvation issues that can lead to hesitation or lean conditions at high rpm. Maintenance access is also improved, with the pump module removable as a single cartridge without dropping the entire tank. The design reflects a commitment to uninterrupted supply under extreme demands.
Calibrated Sending Unit for Reliable Fuel Level Data
The included sending unit is precision calibrated to the internal profile of this tank, delivering true fuel level readings across the full range of travel. Its float mechanism moves freely without binding, so cornering forces and steep angles do not trigger false empty signals. Accurate gauge feedback provides drivers with confidence on long highway runs or spirited canyon drives, preventing unexpected refueling stops. By reporting volume to within a fraction of a liter, the sender helps avoid pump damage from running dry. This level of precision protects both engine performance and fuel system longevity. Consistent feedback also simplifies trip planning and reduces range anxiety.
All Inclusive Kit Components for Streamlined Installation
This comprehensive package includes everything needed for a clean, reliable assembly: the tank shell, pump module, sending unit, tank straps, filler neck, vent filter, gaskets and all required hardware. Precision cut seals and molded gaskets ensure a leak free junction at the module flange and filler spud. The vent filter prevents debris entry while allowing proper tank breathing to avoid pressure buildup that can starve the pump. By supplying both upper and lower strap brackets, installers avoid trips to the parts store and maintain a consistent build quality. Even those new to EFI conversions can complete the job without hunting for missing components. The end result is a turnkey transformation that respects the car's heritage while upgrading performance and reliability.
