LS EFI Fuel Tank Kit with 400 LPH Pump for 1975-1979 Chevy Nova/Ventura
Tackling an LS engine swap in a 1975 through 1979 Chevy Nova or Pontiac Ventura often runs into a common snag when the stock tank cannot keep pace with the fuel demands of a 550 hp engine. The 1975 to 1979 Nova EFI Fuel Tank Kit - 400 LPH Pump provides a reliable supply to prevent starvation and supports engines up to 550 hp without custom modifications. Engineered to fit the X Body frame of Nova and Ventura models, it drops into factory mounting points for a true bolt in installation and maintains proper venting under all throttle positions. Every component from the tank module and sending unit to the vent filter comes ready for a straightforward setup, so installers spend less time fitting parts and more time on tuning.
Seamless X Body Integration for Precision Fit
This fuel tank kit is engineered to match the underbody contours of the 1975–1979 Chevy Nova and Pontiac Ventura X Body chassis, ensuring every mounting hole and bracket aligns exactly as the factory intended. By maintaining original frame geometry, the assembly drops in without trimming or fabrication, reducing setup time and eliminating error points in alignment. This precision fit also preserves proper venting behavior under all throttle conditions, so your LS conversion breathes reliably through every corner and straightaway.
Consistent Fuel Pressure with 400 LPH Walbro Pump
The in-tank 400 LPH Walbro pump delivers a steady flow rate capable of supporting supercharged or 550 hp naturally aspirated LS engines. Its design maintains stable pressure during sustained acceleration and extended high speed runs, preventing fuel starvation when the demand peaks. Consistent delivery is crucial for precise air-fuel control, which translates directly into crisp throttle response, optimal power output and tuning flexibility at the track or on the street.
Streamlined Assembly for Faster Swap Projects
All components arrive preassembled and organized to guide both novice and professional installers through each step without guesswork. The sending unit, fuel module and vent filter mount with factory-style seals and hardware, while included tank straps and gaskets speed removal of the old tank and installation of the new one. This clear, linear process cuts tool changes and downtime, letting shops and DIY enthusiasts stay on schedule and focus on calibration instead of fitment hurdles.
Robust Construction for Dependable Operation
Every element of the kit uses carefully selected materials to resist corrosion and withstand constant exposure to ethanol blends and high heat. Steel straps and mounting hardware feature rust-resistant finishes, while premium seals maintain integrity under vibration and temperature swings. This attention to durability means the system holds pressure and resists leaks over long term use, minimizing maintenance and protecting your investment in an LS conversion.
