1968 Impala EFI Fuel Tank Kit with 400 LPH Pump
When retrofitting a modern EFI system into a 1968 Impala, this fuel tank kit pairs a 400 LPH Walbro pump with an integrated sending unit to meet the steady fuel demand of an LS engine swap. Its steel shell is stamped to the original B Body dimensions to deliver a precise fit with factory frame rails without any cutting of the floor pan. Installation remains straightforward thanks to complete hardware and a one piece module that unites pump, sender, and filter sock. Drivers will value accurate fuel level readings throughout the tank's range and consistent flow under sustained throttle.
400 LPH Walbro Pump Ensures Consistent High-Flow Performance
The Walbro 400 liter per hour pump is calibrated to supply a steady stream of fuel that meets the demands of both boosted and naturally aspirated LS conversions. By maintaining consistent flow under heavy throttle, it prevents fuel starvation and supports up to 750 horsepower applications. The in-tank location also helps dissipate heat and reduces stress on the pump, extending service life. Drivers benefit from smoother throttle response and reliable delivery during street cruising or track use.
Steel Tank Construction Engineered for Durability
This fuel tank uses thick stamped steel formed to the exact dimensions of the 1968 B Body Impala chassis, preserving factory mounting points and frame rail alignment. Its robust shell resists deformation from road debris and road vibration, ensuring the unit retains its shape over time. The welded seams undergo quality checks to guard against leaks and corrosion in harsh environments. As a result, the tank delivers dependable service season after season.
Integrated Module with Fuel Sender Enhances Accuracy
A single assembly combines the pump, filter sock and sending unit into one accessible module that mounts directly in the tank. This design positions the sender at the ideal level in the reservoir, producing precise fuel level readings across all driving conditions. The robust electrical connectors resist corrosion, while the built-in filter sock captures contaminants before they reach the pump. Together, these features streamline maintenance and troubleshooting by keeping critical components in a single location.
Complete Kit Layout Streamlines DIY Installation
All necessary components arrive in one package, including tank straps, filler neck, vent filter, gaskets and mounting hardware for a direct swap of the original tank. Preassembled flanges and matched brackets allow you to remove the old unit and lower in the new assembly without fabricating parts. Clear, step-by-step instructions guide you through fuel line disconnection, wiring and reassembly. The result is a clean, professional install that restores modern EFI performance without a workshop visit.
