1968-1969 Chevy Nova LS and LT EFI Fuel Tank Kit 400 LPH Pump
Builders tackling a swap from an original Chevy Nova powerplant to a modern LS or LT engine in a 1968 to 1969 shell demand consistent fuel delivery under high rpm and boost and this EFI Fuel Tank Kit with its 400 LPH pump meets that requirement. The internal Walbro module resides inside precision baffles in a US steel tank to minimize heat soak and turbulence and to preserve steady pressure during spirited driving or forced induction. Installation aligns with the factory underbody openings so you can bolt the assembly in place without cutting steel or welding new mounts. By keeping fuel starvation at bay through sustained loads you safeguard injector pulse and throttle response across the full rpm range.
In-Tank Walbro Module for Temperature Stabilization
The 400 LPH Walbro pump is fully submerged inside the steel tank baffles to use the surrounding fuel as a coolant. By immersing the pump, the design minimizes heat soak during extended high rpm or boosted operation, preventing fuel temperature from rising and preserving density for reliable atomization. Surrounding baffles also reduce fuel movement inside the tank, cutting turbulence and cavitation risk so that pressure remains even under sudden acceleration or sustained cornering. This stable environment ensures injector pulse width stays accurate for crisp throttle response across the entire engine speed range. Additional protection from vibration and impacts extends module life in harsh driving conditions.
Precision Bolt-In Fitment with Factory Chassis Openings
Every bracket strap and gasket in this kit matches the original 1968-1969 Chevy Nova underbody openings so you can install the fuel tank without cutting sheet metal or welding new mounts. The filler neck aligns with the factory position to maintain stock ground clearance and body profiles. This precise engineering saves hours in fitment adjustments and eliminates alignment issues that can occur with universal or custom solutions. Technicians benefit from a straightforward process that mirrors the original installation procedure, resulting in a clean undercarriage layout and simplified quality control. The result is a professional appearance with factory level integration.
US Steel Construction for Rigidity and Leak Prevention
Critical load bearing components including the tank shell, mounting straps and pump housing are fabricated from US sourced steel for superior strength under road shock and lateral g forces. Precision molded gaskets form robust seals at each junction, preventing leaks during rapid pressure swings in spirited driving or forced induction scenarios. The integrated vent filter blocks airborne debris and water entry, protecting sensitive EFI components downstream. The sending unit float is calibrated for accurate fuel level readings even under hard acceleration or sustained cornering loads. This thoughtful combination of materials and sealing methods ensures the assembly remains secure, leak free and reliable over many seasons of performance driving.
