1967 Impala EFI Fuel Tank Kit with 255 LPH Pump
When fitting an LS or LT powerplant into a 1967 Impala, a tank that locks in stable fuel pressure under load is vital. This 1967 Impala EFI Fuel Tank Kit with 255 LPH Pump uses a three quarter inch deeper bowl and five inch shorter footprint to drop into factory B-body mounts and the original frame position. Constructed from corrosion resistant stainless steel and supplied with a 255 LPH Walbro unit, it supports up to 550 horsepower while maintaining EFI fuel delivery under load. Every kit ships with an integrated sending unit along with straps, gaskets and mounting hardware for a direct swap that preserves ride height and ground clearance.
Advanced Sump Geometry for Consistent Fuel Pickup
The three quarter inch deeper tank bowl increases fuel capacity while keeping the center of gravity low, ensuring the pickup remains submerged during aggressive acceleration and tight cornering. Shortening the tank footprint by five inches allows direct installation into the factory frame location without cutting or welding, yet preserves a stable fuel supply even as the vehicle experiences rapid direction changes. The carefully shaped sump reduces turbulence around the intake, preventing air ingestion when the car sloshes through turns. Coupled with a swirl free inlet on the integrated pump module, this design delivers uninterrupted EFI operation under load.
Comprehensive In Tank Module Streamlines Assembly
This all in one fuel module encloses the 255 LPH Walbro pump, sending unit, vent filter and mounting hardware into a single assembly that drops directly into the stainless steel tank. By integrating these elements, the kit eliminates the need for separate external fittings and brackets, reducing installation time and potential leak points. Included tank straps, gaskets and filler neck fit the stock mounting positions, preserving ride height and ground clearance. Both seasoned shops and DIY builders benefit from fewer parts to manage and a more straightforward assembly process.
Durable Stainless Steel Fabrication Ensures Long Service
Constructed from 304 grade stainless steel, the tank resists corrosion and chemical attack from ethanol blends, offering far greater longevity than mild steel or plastic options. TIG welded seams create a fully sealed assembly capable of withstanding vibration and thermal expansion over thousands of miles. The smooth interior surface minimizes sediment buildup and simplifies periodic cleaning, while exterior polish retains resistance to road salts and environmental contaminants. This robust fabrication guarantees dependable performance for daily driving or weekend track outings.
Optimized Pump Placement for Reliable High Demand Performance
Positioning the 255 LPH Walbro pump inside the tank bowl keeps it immersed in fuel for cooler operation and reduced noise compared to external mounts. This configuration uses the tank as a heat sink, lowering fuel temperature rise and preserving density for steady pressure under heavy throttle. By maintaining consistent flow rates even during spirited driving, the setup supports engines up to 550 horsepower without risk of vapor lock or starvation. An integrated sending unit provides accurate level readings, removing uncertainty at the pump.
Rest assured this assembly delivers consistent EFI pressure under load. For the same fuel tank but with a 400LPH pump see our 1967 Impala EFI Fuel Tank Kit - 400 LPH Pump.
