1971-1972 Pontiac GTO/Lemans EFI Fuel Tank with 400 LPH Pump for LS and LT Swaps
When converting a 1971 and 1972 Pontiac GTO or Lemans to LS or LT power, space limitations around the exhaust and rear tires demand a fuel tank that fits precisely and maintains pressure under high load. The EFI Fuel Tank Kit uses a notched tank design with a fuel pump module inside the reservoir housing a 400 LPH Walbro pump rated for 550 horsepower and above. An integrated sending unit ensures accurate level readings, while included straps, filler neck, vent filter, gaskets and hardware deliver a complete package. This comprehensive EFI conversion kit streamlines installation and aligns with factory frame contours without modification.
Precision Engineered Fuel Storage
The 1971-1972 GTO or Lemans EFI fuel tank kit delivers a notched design that clears exhaust components and rear tires without any trimming or guesswork. Each tank is shaped to match the factory frame rails and ensures the stock suspension travel remains unaffected. This direct fit solution removes interference concerns, so you can install the tank in minutes and regain full underbody clearance. By adapting to the unique contours of the Pontiac floor pan, the kit provides secure mounting points and consistent fuel capacity across every installation.
Integrated Fuel Pump and Module Assembly
At the heart of the kit lies a 400 LPH Walbro pump capable of supporting more than 550 horsepower. The pump sits inside an enclosed module that also holds the fuel level sending unit. This all-in-one assembly means fewer seals and hose connections, reducing the chance of leaks and electrical faults. Quiet in operation and proven in high demand applications, the module maintains stable pressure under rapid throttle transitions. Drivers will notice an immediate improvement in throttle response and idle consistency once the engine is fed by this balanced delivery system.
MuscleRods Approved Fitment for GTO and Lemans
This comprehensive EFI conversion kit is tailored for 1971 and 1972 Pontiac GTO and Lemans models equipped with LS or LT engines. It integrates seamlessly with MuscleRods mounting hardware to guarantee correct engine placement and precise driveline angles. By aligning the pump bracket and body mounts to the MuscleRods standard, the kit eliminates mismatches that can lead to vibration, misalignment, or premature wear. Every component in the package has been tested on dedicated prototype installations to confirm ease of assembly, proper fuel flow, and reliable fuel level readings on the original gauge.
