1969-1970 Impala EFI Fuel Tank Kit with 400 LPH Pump
When converting your 1969 to 1970 Impala to EFI you need a tank that fits precisely and feeds a hungry LS powerplant. This assembly combines a deeper galvanized steel reservoir with a 400 LPH Walbro pump to maintain steady pressure and support engines up to 750 horsepower. Precision contouring ensures bolt in alignment with factory crossmembers and sheetmetal lines without trimming or filler work. The durable powder coat finish resists corrosion and wear for reliable service life. Installers benefit from included hardware and plug and play compatibility with any LS engine swap setup, eliminating guesswork in component sourcing.
Internal Pump Placement Maximizes Flow Stability
The in tank design places the 400 LPH Walbro pump at the heart of the fuel column. This location ensures constant fuel coverage under heavy loads and cornering. It reduces risk of vapor lock and cavitation by keeping fuel around the pump inlet. That in turn yields steady pressure even when demands peak up to 750 horsepower output. A direct benefit of internal mounting is lower noise generation and reduced heat stress on the unit. Continuous immersion support extends pump life by reducing dry run hours and maintaining reliable operation.
Tailored Tank Profile for Precise B Body Fit
The reservoir is crafted three quarters of an inch deeper and five inches shorter than the original tank to clear crossmember structures. Its contours trace the factory underbody lines of the 1969 and 1970 Impala chassis without requiring body work or filler. Such precision translates to a bolt in process that preserves original ground clearance and frame alignment. This refined geometry also supports a variety of LS powerplant arrangements under the rear floor. It lowers the risk of pinched hoses or interference with exhaust components, so installers can trust the shape to integrate seamlessly with existing sheetmetal sweeps.
Galvanized Construction with Durable Coat
Galvanized steel forms the basis of the tank body, providing inherent corrosion resistance against moisture and road chemicals. A robust powder finish adds a secondary barrier to guard against abrasion and impact damage. Weld seams undergo quality checks to confirm airtight joints and structural strength under high volume flow conditions. Together these coatings reduce maintenance intervals and guard integrity over years of use. The result is a reliable vessel that will not rust or fail under relentless service demands.
Unified Kit Design Eases Installation
All necessary parts come in a single package to streamline the build process. The kit includes the fuel pump module with sending unit, vent filter, filler neck and mounting hardware tailored to the tank profile. Each component is matched to the reservoir shape and flow requirements to eliminate fit surprises during assembly. Gaskets are pre sized to ensure a tight seal and prevent leaks from the start. This consolidated approach saves time by removing uncertainty about part compatibility and fit so technicians can move quickly from box to bolted unit.
