EFI Fuel Tank Kit with 400 LPH Pump for 1969-1970 Impala
Swapping an LS powerplant into a 1969 or 1970 Impala often stalls at sourcing a tank that maintains fuel pressure under heavy acceleration while matching the B Body chassis. With precision contouring to the original underbody pattern this EFI fuel tank kit installs on factory crossmembers without trimming or filler work and delivers consistent flow for engines up to 750 horsepower. The galvanized steel reservoir and integrated 400 LPH Walbro pump guard against corrosion and vapor lock by keeping the inlet submerged at all times. Installers will value the plug and play compatibility and included hardware that removes guesswork from every step of the swap.
Efficient Fuel Supply with In Tank 400 LPH Walbro Pump
The in tank placement of the 400 LPH Walbro pump ensures the inlet remains covered by fuel even during hard acceleration or tight cornering. By keeping the unit submerged the design reduces the risk of cavitation and vapor lock that can cause erratic pressure drops and hesitation. This steady flow supports engines up to 750 horsepower with consistent delivery across all driving conditions. Quiet operation and lower operating temperature also help extend service intervals and improve reliability over repeated use.
Precision Tank Profile for 1969 1970 Impala B Body Chassis
Engineers sculpted the reservoir to be three quarters of an inch deeper and five inches shorter than the original tank, following the factory B Body lines for 1969 and 1970 Impala models. This precise contouring matches crossmember locations and maintains original ground clearance without any trimming or filler work. It also avoids interference with exhaust hangers and brake lines, preserving underbody integrity. Installers save hours by bolting the unit into existing mounts for a true fit on the Impala chassis.
Galvanized Steel Body with Powder Coat Finish
Constructed from galvanized steel the fuel tank resists moisture and road salt that commonly attack bare metal. A durable powder coat finish adds a secondary barrier against abrasion and chemical exposure, keeping the reservoir in service through years of use. Weld seams receive inspection to verify airtight joins that withstand vibration and pressure pulsation in high output applications. The result is a corrosion resistant vessel that maintains structural strength and resists leaks over time.
Complete Kit Components for Streamlined LS Conversions
This all inclusive kit lets technicians move through each step without sourcing parts from multiple vendors. It includes the 400 LPH pump module, sending unit, straps, filler neck, vent filter, gaskets and all necessary hardware, each component matched to the tank profile and flow requirements. Gaskets seal precisely to the fittings and fuel hoses connect without adapters, while the sending unit delivers accurate gauge readings in the stock cluster. By providing every required item the kit simplifies installation and cuts total project time.
Built for lasting reliability under hard acceleration and tight cornering. To try a different flow rating find the same fuel tank but with a 255LPH pump in our 1969-1970 Impala EFI Fuel Tank kit - 255 LPH Pump.
