LS LT EFI Tank with 400 LPH Pump for 1971-1972 GTO Lemans

Optimal fuel delivery under heavy load is ensured by the 400 LPH Walbro pump integrated into the 1971 and 1972 GTO / Lemans EFI fuel tank kit. Engineered for precise bolt in fitment on 1971 and 1972 Pontiac GTO and Lemans A Body models, it streamlines LS and LT swaps while supporting 550 horsepower performance and improving fuel economy for confident cruising.

LS and LT Fuel Tank Kit for 1971-1972 Pontiac GTO and Lemans

Swapping a modern LS or LT powertrain into a classic 1971 and 1972 Pontiac GTO or Lemans requires a fuel delivery system that can handle higher output without hesitation. The 1971-1972 GTO / Lemans EFI Fuel Tank Kit - 400 LPH Pump features a 400 LPH Walbro pump, a tank module, pressure regulator, wiring harness, and all necessary hardware to guarantee direct install in an A Body platform. Designed for straightforward LS and LT integrations, this kit maintains steady fuel pressure during spirited driving while preserving the car's original mounting points.

Exact Fitment for 1971 and 1972 Pontiac GTO and Lemans

This fuel tank kit is engineered to match the original contours and mounting points of the A body chassis, eliminating the need for custom fabrication. By retaining the factory hangers and flange locations, it ensures a direct bolt in replacement that preserves the integrity of the underbody structure. Technicians will find that the tank slides effortlessly into the stock well, reducing alignment checks and trial fitting. The result is a seamless upgrade that honors the car's heritage while accommodating modern fuel delivery demands.

400 LPH Walbro Pump for 550 Horsepower Applications

At the heart of the kit lies a 400 liter per hour Walbro pump designed to support engines producing more than 550 horsepower. This pump maintains a high volume flow rate to meet sudden throttle demands, preventing lean conditions under full load. Walbro's proven design features precision tolerances in the rotor and strainer to ensure consistent performance and long service life. For enthusiasts pushing the limits of LS or LT powerplants, this pump provides the confidence that fuel supply will never become the weak link.

Integrated Module and Pressure Regulator for Consistent Flow

The in-tank pump module works in concert with an adjustable fuel pressure regulator to deliver a steady stream of fuel regardless of driving dynamics. By locating the pump inside the tank, the system benefits from cooling by the fuel itself and reduced vapor lock risk. The pressure regulator maintains ideal rail pressure across varying RPM and load conditions, which is critical for precise fuel-injection timing. Together, these components stabilize combustion and improve throttle response during spirited acceleration or sustained high-speed runs.

Comprehensive Kit Streamlines Installation Process

This all-in-one package includes the Walbro pump, pump module, sending unit, filler neck, tank straps, vent filter, gaskets, and all mounting hardware needed for a direct install. Having every component matched and supplied in a single kit reduces the time spent sourcing parts and ensures each piece is optimized for the GTO and Lemans fuel tank geometry. Installers simply remove the original tank, transfer a few existing lines, and secure the new assembly with the provided hardware. The straightforward process minimizes downtime and delivers a reliable upgrade without guesswork.
