1971-1972 Chevy Nova X-Body EFI Fuel Tank Kit for LS and LT Swaps
For builders adapting an LS or LT powerplant to a 1971 to 1972 Nova X Body, consistent fuel delivery through every throttle change can make or break performance. This EFI fuel tank kit with a strong Walbro unit and a 400 LPH pump remains submerged to prevent heat soak and vapor lock at idle or high rpm. The complete system installs along the original frame rails with no cutting or welding and includes the sending unit, filler neck, straps and all mounting hardware. Developers and hobbyists alike will value the quiet operation and the capacity to support modern engines over 550 hp without fuel starvation concerns.
Immersed Walbro Fuel Pump for Consistent Pressure
The 400 LPH Walbro unit sits fully within the tank to keep its components cool and shielded from engine bay heat. Being submerged eliminates the risk of vapor lock by preventing heat soak during idle and sustained high rpm operation. This immersion also stops cavitation under heavy throttle and supports engines up to 550 horsepower without fluctuation in fuel delivery. With its built-in pressure regulator the pump maintains a steady flow from cruise to wide open throttle, while the surrounding fuel volume muffles noise into a low hum for a quieter cabin experience.
Heavy Gauge US Steel Shell with Integrated Baffle System
Fabricated from thick US steel plate the tank body stands up to road debris impact and resists corrosion over years of service. Inside, precision formed baffles trap fuel against hard cornering and sudden stops to keep the pump inlet submerged at all times. Weld seams receive full sealing and reinforcement beads to prevent fatigue cracks under vibration and temperature swings. A chemical resistant interior finish tolerates modern ethanol blends without seal breakdown, and exterior electrocoating locks out moisture to guard against rust and pitting.
Precision Contour Matching for 1971 1972 Nova X Body Rails
Every curve and notch of the tank follows the original 1971 to 1972 Nova X Body frame rails, delivering a true drop-in fit without cutting or welding. Designers left clearance around the driveshaft tunnel, suspension mounts and exhaust path, so no custom trimming is required. Pre drilled mounting points align with supplied heavy duty straps and hardware for a secure hold while preserving factory ground clearance. By keeping the stock footprint the tank maintains proper weight distribution and handling balance just as the chassis engineers intended.
Comprehensive Kit for Streamlined LS LT Engine Swaps
This all-in-one fuel system kit arrives with the in tank pump module and sending unit fully assembled and calibrated to match the Nova's original fittings. A molded filler neck and vent filter seal the tank opening with precision gaskets to prevent leaks and vapor emissions. Included straps, rubber insulators and stainless hardware secure the tank while isolating vibration that can stress welds over time. With every component tested in real world LS and LT swap scenarios, builders finish the installation in one session with confidence in fit and function.
