1967 Impala EFI Fuel Tank Kit with 400 LPH Pump
For LS engine swaps in a classic Impala, the 1967 Impala EFI Fuel Tank Kit - 400 LPH Pump solves the twin issues of underwhelming factory flow and complex bracket fabrication. Mounting directly to the B Body frame rails without cutting or welding, this assembly combines a sealed reservoir and integrated sending unit with a 400 LPH Walbro pump rated for engines up to 750 horsepower. Vehicle builders gain reliable fuel pressure on both daily drives and spirited pulls while limiting service points and potential leak paths to a minimum.
Precision B-Body Installation Without Modifications
The fuel tank kit is engineered to drop directly into the 1967 Impala B-Body frame rails with no cutting or welding required. Its contours match the factory underbody geometry to maintain original clearance and structural integrity. This exact alignment speeds up installation by eliminating custom brackets and fitment trials. Whether fitting a stock Impala V8 or an LS engine conversion, builders benefit from a straightforward process that keeps fabrication time to a minimum.
400 LPH Walbro Pump Performance Under Demanding Conditions
At the core of the assembly is a 400 LPH Walbro pump capable of supporting engines up to 750 horsepower, delivering a steady fuel supply during wide open throttle pulls. Its design minimizes cavitation and maintains consistent pressure in both high speed runs and stop-and-go traffic. By avoiding lean spots under load, the pump ensures smooth throttle response and power delivery. This margin of flow capacity also allows room for future power upgrades without changing fuel hardware.
Integrated In Tank Assembly Minimizes Leak Paths
The sealed in-tank module houses the pump, sending unit, and vent filter within a single enclosure, reducing external lines and connection points. Precision-cut gaskets and dedicated mounting hardware create a leak-proof barrier at the filler neck and flange. Consolidating components in one module streamlines maintenance and limits potential failure points. As a result, owners enjoy a reliable, low-service solution that stands up to daily driving demands.
Premium Construction for Corrosion Resistance and Durability
Every component is crafted from materials selected for their resistance to corrosion and mechanical wear. The tank shell retains its shape under repetitive fill and drain cycles, while robust straps and hardware secure it against road shocks and vibrations. Internal parts are shielded from debris by a dedicated vent filter, preserving pump longevity. This combination of design choices delivers a fuel system that remains dependable over years of spirited driving and daily use.
