1971-1972 Chevy Nova X-Body LS/LT EFI Fuel Tank Kit 400 LPH Pump
For builders tackling a 1971 to 1972 Nova X-Body LS or LT engine swap this fuel tank kit with a 400 LPH Walbro pump ensures a cool, consistent fuel supply under idle and wide open throttle. Submerged entirely in a molded US steel tank the pump side steps heat soak that can lead to vapor lock during sustained high rpm use. Installation drops directly onto original frame rails without cutting or welding and internal baffles maintain steady pickup through tight corners. A complete package includes sending unit filler neck straps and hardware so both novices and pros can finish the swap in a single session.
Submerged Walbro 400 LPH Pump Performance
The Walbro 400 LPH unit sits entirely below the fuel level inside the tank to draw a cooler supply and reduce heat soak that leads to vapor lock under sustained high rpm. Its integrated regulator maintains consistent pressure from idle to full throttle, preventing lean spots when you need power most. Immersion also muffles operational noise, transforming pump whine into a quiet hum. By keeping the pump in raw fuel, this design supports supercharged engines and outputs in excess of 550 horsepower without compromise. Simplified plumbing and wiring further clean up the engine bay for a neater installation.
Precision Match to 1971 1972 Nova X-Body Frame Rails
Engineered for direct drop-in onto original frame rails of 1971 and 1972 Nova chassis, the tank eliminates any need for cutting or welding. Precision formed contours clear the driveshaft, suspension pickups and existing exhaust routing while preserving factory ground clearance. Installers slide the tank into position, align the mounting holes and secure it with the supplied straps and bolts. This process removes alignment guesswork and delivers a consistent fit that feels as though GM designed it this way from the factory.
Heavy Gauge Steel Construction with Internal Baffles
Fabricated from thick US steel, the tank resists impact damage and guards against corrosion for years of reliable service. Weld seams receive extra reinforcement to prevent cracking under road vibration or temperature shifts. Carefully placed internal baffles limit fuel movement during hard cornering or abrupt stops, ensuring the pump never starves for supply. A chemically resistant interior finish accommodates modern ethanol blends and protects seals and gaskets against premature wear, keeping fuel delivery stable in every driving scenario.
Complete Kit for Easy LS or LT Installation
This all-in-one package delivers every component needed to tackle an LS or LT swap without last-minute trips to the parts store. The in-tank pump module and sending unit arrive pre assembled to match Nova fuel lines and factory style connectors. Included filler neck, tank straps, vent filter, gaskets and mounting hardware ensure all elements work in harmony. Whether you are a first-time builder or a seasoned professional, the kit streamlines the swap into a single session and keeps your project moving forward.
