1967 Impala EFI Fuel Tank Kit with 400 LPH High-Flow Pump
Swapping an LS powerplant into a classic 1967 Impala often leads to fuel supply shortfalls under load. This 1967 Impala EFI Fuel Tank Kit - 400 LPH Pump meets that challenge by combining a sealed reservoir, integrated sending unit, and a 400 LPH Walbro pump in a single assembly that installs directly onto the B Body frame rails with no cutting or welding required. With contours matched to the factory underbody geometry it preserves original clearance and structure while speeding installation. The 400 LPH pump capacity supports engines up to 750 horsepower to maintain consistent pressure during spirited runs and heavy acceleration.
Seamless Drop In Installation on 1967 Impala B Body Rails
The fuel tank kit is engineered for a true drop in fit on 1967 Impala B Body frame rails without any cutting or welding. Contours follow the factory underbody geometry to preserve original ground clearance and structural integrity, so there is no need for custom brackets or trial fitting. Using existing mounting points speeds installation and reduces alignment errors while keeping the chassis unaltered. Whether installing a stock V8 or an LS swap, builders gain a reversible solution that maintains OEM rigidity and saves fabrication time.
400 LPH Pump Delivering Steady Fuel Pressure for Performance Demands
At its core sits a 400 LPH Walbro pump proven in applications up to 750 horsepower, which provides a margin of flow capacity for spirited driving and future upgrades. Its design minimizes cavitation and sustains steady pressure during wide open throttle bursts as well as in stop start urban traffic. Consistent fuel delivery prevents lean spots under heavy load and promotes smooth throttle response. This pump choice has been validated by high demand performance builds and offers reliable operation under continuous use.
All in Tank Integration Minimizing Leak Paths and Clutter
By housing the pump, sending unit and vent filter within one sealed module, this assembly reduces external fittings and potential leak points. Precision-cut gaskets at the filler neck and flange form a robust seal, and dedicated hardware secures the module firmly in the tank shell. Fewer hose connections mean faster plumbing, lower maintenance and simplified troubleshooting. The integrated sending unit delivers accurate level readings, while the single removal design streamlines access for any service or upgrade.
Robust Construction Ensuring Corrosion Resistance and Durability
The tank shell is formed from premium steel finished to resist corrosion and withstand repetitive fill and drain cycles. Heavy duty straps and mounting hardware lock the unit in place to absorb road shock and vibration without flexing. A dedicated vent filter and reinforced filler neck guard internal components from debris, while high temperature resistant seals and gaskets maintain leak free performance. Material choices prioritize dimensional stability under heat, delivering long term reliability for both daily driving and performance use.
