1971-1972 Chevy Nova LS and LT EFI Fuel Tank Kit with 400 LPH Pump
Fitting an LS or LT powerplant into a 1971-1972 Nova X Body chassis requires precise fuel management and this EFI tank kit with a 400 LPH Walbro pump delivers consistent flow at both idle and high rpm to prevent starvation and vapor lock. Submerged entirely in a US steel tank the pump avoids heat soak and cuts operational noise for a quiet run. Installation aligns with the original frame rails and skips any need for cutting or welding to preserve chassis integrity. The complete package includes a sending unit, filler neck, straps and hardware so both rookies and veteran builders can finish the swap in a single session.
Optimized Fuel Delivery with Submerged Walbro Pump
The Walbro 400 LPH pump is fully submerged within the tank's fuel volume to keep its components cooler than an external mount and to cut heat soak that can trigger vapor lock during sustained acceleration. By drawing fuel directly in an immersion environment the unit avoids cavitation at high rpm and maintains consistent delivery under any throttle demand. Its built in regulator sustains pressure evenly from idle speed through wide open throttle, preventing lean conditions that can harm engine performance. Immersion inside the tank also reduces operational noise, transforming a loud whine into a quiet hum that preserves cabin comfort. This approach supports forced induction setups as well as normally aspirated engines producing over 550 horsepower without risk of fuel starvation. Simplified wiring and plumbing layouts free up space in the engine bay for a cleaner presentation and faster assembly times.
US Steel Construction with Integrated Baffles for Stable Flow
Fabricated from thick US steel, the tank shell offers high structural rigidity and resistance to corrosion, safeguarding fuel delivery against road debris impacts and environmental wear over years of service. Carefully engineered internal baffles confine fuel during hard cornering or sudden stops, ensuring the pump inlet remains submerged under all driving conditions and eliminating fuel starvation. Weld seams are fully sealed and receive reinforcement beads to withstand constant vibration and temperature cycling without fatigue cracks. The interior surface is coated with a chemically resistant finish that tolerates modern ethanol blends, preventing seal degradation and fuel contamination. A protective electrocoating on the exterior further shields against rust and pitting. Together these materials maintain stable fuel flow and extend the tank's service life under demanding conditions.
Precision Fit for 1971 until 1972 Nova X Body Frame Rails
Every contour of the tank has been precision formed to match the original 1971 through 1972 Nova X Body frame rails, allowing a drop in without any cutting or welding and preserving the vehicle's factory ground clearance. Designers cleared critical zones around the driveshaft tunnel, suspension mounting points and exhaust routing to eliminate interference and avoid the need for custom modifications. Installation simply involves sliding the tank into position, aligning the pre drilled mounting holes, and securing it with the supplied heavy-duty straps and hardware. This direct fit reduces installation time and removes alignment guesswork, giving installers confidence that the tank will integrate just as GM intended. The factory style ground strap attachment and vent filter port further preserve original system functions. Maintaining the stock footprint also helps retain proper weight distribution and handling balance.
Complete Fuel System Kit for Simplified LS or LT Swap
This all in one kit delivers every component needed for an LS or LT engine swap, preventing last minute trips to the parts store and keeping the project moving forward in a single build session. The in tank pump module and sending unit arrive fully assembled and calibrated to match the Nova's original fuel line fittings and electrical connectors, ensuring plug and play compatibility. A molded filler neck, vent filter, and precision molded gaskets seal perfectly against the tank opening to prevent leaks and vapor emissions. Included heavy gauge tank straps, rubber insulators and stainless steel hardware ensure a secure mounting while isolating vibration. Whether you are a first timer or a seasoned mechanic the kit streamlines the installation process and eliminates the need to source additional parts. Each component has been tested in real world LS and LT swap scenarios to confirm fit and function before it reaches the builder's garage.
