EFI Fuel Tank Kit with 255 LPH Pump for 1967 Impala
With an LS or LT swap demanding steady supply, this 1967 Impala EFI Fuel Tank Kit - 255 LPH Pump solves the stock tank's shortcomings by offering increased fuel capacity and a compact profile that drops into the factory rails without trimming. By deepening the bowl by three quarters of an inch and cutting the length by five inches, the assembly preserves ground clearance and maintains tank placement. Built completely from corrosion resistant stainless steel, it includes a Walbro pump rated at 255 LPH, an integrated sending unit and all mounting hardware. In spirited driving the lowered pickup point keeps the EFI fuel delivery uninterrupted even under hard acceleration and cornering.
Engineered Sump Geometry for Uninterrupted Fuel Flow
The deeper fuel bowl captures additional capacity while positioning the pickup at a lower point than stock hardware. This geometry ensures that even under heavy acceleration or sustained cornering the Walbro pump remains enveloped by liquid rather than drawing air. Shortening the length by five inches allows direct fit to the original frame rails without any trimming or modification to brackets and floor pans. Additionally the contoured shape of the sump area minimizes swirl and reduces turbulence around the inlet screen. The result is uninterrupted delivery of fuel to engines rated up to five hundred fifty horsepower even when fuel levels run low or lateral forces shift the fluid mass. This precise design is essential for maintaining consistent pressure and avoiding vapor lock in dynamic driving scenarios.
Integrated Fuel Module Streamlining Swap Process
Combining the fuel pump sending unit and vent filter into a single assembly reduces the number of parts and leak points that installers must manage. All necessary gaskets straps filler neck and mounting hardware arrive ready for fast attachment using existing factory mounting holes. The unified module simplifies the retro fit process by removing the need to fabricate external brackets or run additional hoses. This clear arrangement also keeps the fuel system contained inside the final assembly for a cleaner undercar area and simplified future maintenance. Even less experienced home mechanics can achieve a reliable bolt in application that mirrors the original equipment style and maintains an uncluttered engine bay.
Precision Stainless Steel Construction Resisting Corrosion
Fabricated from premium grade stainless steel the tank resists ethanol blends corrosive road salts and the wear associated with fluctuating temperatures. Weld seams executed with precision create a fully sealed envelope that holds up against the flex and vibration inherent in a vintage chassis. Inside the smooth metal surface prevents sediment accumulation around the pump inlet and extending service intervals for in line filters. The bright finish on the exterior sheds grime and moisture rather than trapping contaminants against bare metal. Over time this choice of construction material delivers peace of mind by reducing the likelihood of rust and cutting down on routine upkeep.
Submerged Pump Placement Enhancing Cooling and Quiet Operation
Locating the 255 LPH Walbro pump within the fuel reservoir takes full advantage of surrounding liquid as a natural cooling agent. By keeping the unit immersed the assembly avoids the heating issues that can arise with external pump mounts and prevents fuel temperature rise during extended use. This stable thermal environment helps preserve fuel density which in turn sustains consistent pressure to the injectors at high engine loads. Submerged placement also dampens mechanical noise so that pump operation becomes nearly inaudible from inside the cabin. Together these factors ensure that fuel delivery stays rock solid even under track day stress or extended highway runs.
Designed for lasting reliability this fuel tank kit delivers consistent performance under spirited driving. For the same fuel tank but with a 400LPH pump see our 1967 Impala EFI Fuel Tank Kit - 400 LPH Pump.
