Precision Fitment with Original B-Body Mounting Points
This fuel tank is engineered to align perfectly with the frame rails and strap bosses of 1961 through 1964 Chevy Impala BBody chassis. By preserving the factory filler neck location and bolt pattern, the assembly installs without altering the frame or chassis. Technicians benefit from a true drop in solution that retains original ground clearance and body proportions, making the modern EFI upgrade completely invisible from the outside. With this exact fitment, installers avoid time-consuming modifications and ensure the finished vehicle maintains its authentic stance.
In-Tank Pump Immersion for Noise Suppression and Cooling
The high-efficiency 255 LPH Walbro pump resides fully submerged in the tank, drawing surrounding fuel over its motor housing to dissipate heat and extend service intervals. Immersion also isolates vibration and flow noise, delivering a quieter cabin even under load. By combining pump, filter and sending unit into one sealed module, this design cuts down on plumbing and leak points while ensuring constant pressure and eliminating the risk of vapor lock during spirited driving. The result is a refined driving experience that treats both high output and daily commuting with equal poise.
Consistent Fuel Delivery for Up to 550 Horsepower LS Engines
Capable of supporting LS swaps producing up to 550 hp, the 255 LPH pump sustains stable pressure across the entire rev range-from idle through wide open throttle. This ample flow rate helps maintain the ideal fuel to air ratio, preventing lean conditions that can harm internal components. Drivers will notice sharper throttle response and improved fuel efficiency under both light cruising and hard acceleration. Whether the Impala serves as a weekend cruiser or track car, this system provides the margin required for safe, reliable high output operation.
Complete Bolt-In Kit Streamlining EFI Installation
Every component needed for a seamless EFI fuel upgrade ships in one package, including the in-tank pump module, sending unit, tank straps, filler neck, vent filter, gaskets and hardware. By consolidating parts for the 1961–1964 Impala B-Body, installers eliminate compatibility concerns and reduce downtime sourcing separate items. The preassembled tank simply bolts into existing mounts and ties into the factory fuel lines and wiring harness, allowing builders to focus on engine calibration and tuning rather than part matching. This all-inclusive approach shortens project time and ensures correct integration from the outset.
