1967 Impala EFI Fuel Tank Kit with 400 LPH Pump
Tackling the extra fuel flow requirements of an LS swap in a 1967 Impala demands more than a stock reservoir and this EFI kit delivers 400 LPH via an integrated in-tank module. Designed to drop straight into factory underbody rails without any cutting or welding, it matches original frame contours to preserve ground clearance and chassis strength. With the Walbro pump installed inside the sealed steel reservoir, drivers enjoy steady pressure for both daily cruising and spirited exits while maintenance stays simple. By housing the pump, sender and vent filter in one assembly, this solution cuts leak points and streamlines system troubleshooting.
Tailored B Body Frame Contour for Direct Fitment
The 1967 Impala EFI fuel tank kit is stamped to mirror the original frame rail curves on factory B Body chassis, allowing it to drop into place using existing mounting points without cutting or welding. By preserving the factory underbody geometry and ground clearance, the design avoids interference with suspension and brake components while maintaining ride height and chassis balance. Installers benefit from reduced setup time and the elimination of custom bracket fabrication. This direct fit approach supports modern EFI conversions without altering the classic frame and safeguards structural integrity over time.
Integrated Fuel Module Reducing Leak Points
The in tank assembly houses the fuel pump, sending unit and vent filter within a single sealed steel reservoir, minimizing external plumbing and potential seepage. Precision molded gaskets at the module flange and filler neck deliver a secure barrier that stands up to repeated fill cycles. A single access plate allows pump or filter replacement without dropping the entire tank, speeding maintenance and cutting service costs. With fewer hose connections and fittings to inspect, system troubleshooting is more straightforward and reliable for daily driving or spirited outings.
Walbro 400 LPH Pump Supporting Up to 750 hp
Central to this kit is a 400 liter per hour Walbro fuel pump engineered to supply builds up to 750 horsepower with steady pressure under high demand. Its integrated bypass and regulator design prevent cavitation at high rpm and ensure consistent flow during full throttle or rapid load transitions. That reserve capacity supports future performance upgrades or forced induction without the need for a secondary pump. Drivers will notice sharper throttle response and precise air fuel control whether cruising on the highway or pushing hard through corners.
Robust Steel Construction for Underbody Protection
The reservoir shell is formed from heavy gauge steel treated with a corrosion resistant coating to endure road debris, salt and chemical exposure. Reinforced straps and high quality hardware secure the tank firmly to the undercarriage, absorbing vibration and shock without flex or fatigue. The filler neck aligns perfectly with the factory opening and features heat resistant seals that maintain a leak free barrier in extreme conditions. Together, these material choices and assembly methods ensure dependable service life and consistent performance with minimal upkeep.
