1968 Chevrolet Impala EFI Fuel Tank Kit with 400 LPH Pump
Swapping an LS powerplant into a 1968 Impala chassis demands reliable fuel supply, and this 1968 Impala EFI Fuel Tank kit - 400 LPH Pump ensures steady delivery under sustained throttle. Its stamped steel shell follows the B Body frame rails to preserve factory mounting points without cutting the floor pan, cutting installation uncertainty. By integrating the Walbro 400 liter per hour module with sender and filter, installers gain precise pressure control and consistent fuel flow during spirited runs. The complete hardware set including straps, filler neck and vent components supports a single session installation for modern injection performance in a classic Impala.
Tailored Steel Construction Preserving Factory Mounts
The fuel tank shell is crafted from heavy gauge steel that mirrors the original 1968 B-Body frame rail contours, eliminating the need for floor pan modification. By preserving all factory mounting points, the assembly fits flush with the chassis and retains structural integrity under road stress. Fully welded seams are treated with corrosion-resistant sealant, preventing moisture intrusion and extending service life. Matching the Impala's original profile also reduces vibration and drivetrain noise, ensuring the tank remains secure even during spirited acceleration. This precise stamping approach balances classic appearance with modern durability.
Integrated Pump Module Simplifying Plumbing
Combining the pump, sending unit and internal filter into a single module streamlines hose routing and electrical connections. Positioning the sender at an optimal height guarantees accurate fuel level readings, even under heavy acceleration or steep inclines. A sock filter at the inlet traps debris before it reaches the pump, reducing wear and extending maintenance intervals. Corrosion-resistant terminals and quick-disconnect connectors further improve reliability and simplify troubleshooting. This integrated design cuts installation time by eliminating separate assemblies and reduces the chance of leaks or misrouting.
400 LPH Walbro Module Ensuring Consistent Pressure
The included Walbro 400 liter per hour pump is engineered to support high-output LS engine conversions of up to 750 hp, offering a generous flow margin for naturally aspirated or boosted applications. Being fully immersed in fuel, the pump benefits from continuous cooling, which helps prevent overheating during extended high-load operation. This capacity maintains stable fuel pressure at elevated engine speeds, eliminating the risk of lean spots and hesitation. Drivers will notice smoother throttle response and dependable delivery, whether cruising on the highway or launching from a stop. The robust design also tolerates variations in fuel temperature, ensuring performance consistency in diverse conditions.
All Inclusive Kit for Quick Installation
This complete package brings together tank straps, filler neck, vent filter, gaskets and all necessary hardware to complete a direct swap in one session. Precision-formed brackets align with existing holes in the Impala frame rails, guiding installers from fuel line disconnection through final torque checks. The included instruction sheet lays out each step in clear detail, minimizing trips to the parts store and reducing guesswork. Because each component is preassembled or clearly identified, technicians can finish the installation in a standard workday without specialty tools. The result is a ready-to-run EFI system that modernizes fuel delivery in a classic Impala with minimal downtime.
