1971-1972 Pontiac GTO/Lemans EFI Fuel Tank Kit for LS and LT Engines
When fitting an LS or LT power plant into a 1971 to 1972 Pontiac GTO or Lemans chassis, maintaining consistent fuel delivery under heavy throttle is paramount and this EFI fuel tank with integrated 400 LPH pump addresses that need. Its corrosion resistant steel shell aligns with original hangers and flange locations on the A Body frame without cutting or welding, preserving chassis integrity during the swap. Featuring an internal pressure regulator, the module sustains rail pressure for engines exceeding 550 horsepower, prevents vapor lock and cuts suction line length to reduce cavitation.
Precision Alignment with Factory A-Body Mounting Points
The fuel tank shell is CNC formed from corrosion resistant steel to mirror the underbody contours of the 1971 and 1972 Pontiac A-Body chassis. Precision machining aligns inlet flanges and hanger brackets within fraction of a millimeter tolerances so the tank engages factory hangers without modification. This accurate interface preserves frame strength and exact clearance for control arms and brake lines. By avoiding cutting or welding, installers retain steel integrity and original crumple zones for safety and longevity. The result is a direct mount unit that fits like the factory tank yet supports modern EFI requirements.
In Tank Pump Configuration for Cooling and Flow Stability
Housing the 400 LPH fuel pump entirely within the tank provides critical thermal management and flow consistency during intense driving. Submerged operation lets the pump shed heat directly into the fuel, preventing temperature spikes that can cause vapor lock or premature wear. The Walbro design uses tight rotor clearances and a stainless steel strainer to minimize turbulence and cavitation under heavy cornering or rapid throttle transitions. A steady flow rate of 400 liters per hour supports LS and LT engines above 550 horsepower without pressure loss. This stable delivery helps protect injectors from lean spikes and maintains efficient combustion.
Tunable Pressure Regulator Tailored to Engine Demands
The integrated pressure regulator sits alongside the pump and holds rail pressure to a specified set point across all operating conditions. Accurate pressure control is vital for multi point injection systems, where minor swings can alter air fuel ratios and affect throttle response. An internal adjustment screw allows technicians to match regulator output to specific injector flow rates or boost levels for supercharged or turbocharged LS and LT applications. Short suction lines reduce the risk of flow drops under high G loads, ensuring consistent pressure from idle through redline. Centralizing regulation inside the tank also simplifies underhood plumbing and minimizes clutter.
Comprehensive Hardware Package for Streamlined Swaps
Every component needed to complete the fuel system swap ships in a single kit, eliminating the need to source parts separately. Included are the in tank pump module, sending unit calibrated for the stock gauge output, heavy duty tank straps, matched filler neck, inline vent filter, molded gaskets and all mounting bolts, nuts and washers. Each item is engineered to fit the tank's contours precisely, allowing reuse of original fuel lines and wiring harness connections with minimal adaptation. Fuel resistant gaskets and O rings prevent leaks and withstand ethanol blended fuels. This complete hardware package transforms a complex conversion into a straightforward installation with reduced labor and fewer potential errors.
