1968-1969 Chevy Nova LS and LT EFI Fuel Tank Kit with 400 LPH Pump
If you plan to drop a modern LS or LT engine into your 1968 or 1969 Chevy Nova this EFI fuel tank kit ensures a reliable fuel stream under demanding driving conditions. It features an internal Walbro pump module submerged in the tank to reduce heat soak and turbulence while maintaining constant fuel pressure through sustained high rpm or forced induction use. Engineers have matched every strap gasket and bracket to the original underbody openings for a bolt in fitment with no cutting or welding. Consistent delivery protects against lean conditions whether you are on the street or the track.
Internal Walbro Pump Placement for Steady Fuel Flow
The 400 LPH Walbro pump module is fully submerged inside the steel tank, using its own reservoir as a cooling medium to prevent heat soak and maintain even temperatures. This design minimizes turbulence around the pump inlet, which in turn reduces cavitation risk and preserves consistent pressure output throughout the engine's entire rpm range. By keeping the pump immersed, the system achieves uniform fuel delivery even when supporting forced induction or outputs above 550 hp. Engine response remains smooth from idle through full throttle thanks to stable injector pulse characteristics, critical for both street driving and track use. The internal location also extends pump life by shielding it from underbody shocks and vibrations.
Bolt In Fitment Preserving Underbody Contours
Every bracket, strap and gasket in this kit is engineered to align with the original Nova tank openings, allowing a direct bolt-in installation with no cutting or welding required. The filler neck positions exactly as the factory part did, restoring the chassis profile beneath the rocker panels for a seamless appearance. This faithful replication of the stock mounting points preserves the vehicle’s structural integrity and eliminates the need for aftermarket adapters or custom brackets. Installers save time and avoid fitment headaches by relying on precision-matched hardware that secures the tank in place without modification. The result is a professional quality undercarriage that retains its classic contour.
Durable Assembly with Vibration Resistant Pump Housing
To withstand the rigors of spirited driving, the pump housing and metal straps are built from robust materials capable of resisting road shock and high-g cornering forces. Precision molded gaskets seal out leaks under rapid pressure changes, while the integrated vent filter keeps contaminants away from injectors. The sending unit's float mechanism is calibrated to deliver accurate fuel level readings even during hard acceleration or sustained cornering. Each component is designed for longevity, ensuring that the assembly remains secure and leak-free through years of daily driving or track days. This rugged construction underpins reliable performance in demanding automotive environments.
Comprehensive Kit for Streamlined EFI Conversion
This all-in-one fuel tank kit includes the 400 LPH pump, in-tank module, sending unit, filler neck, vent filter, gaskets, straps and all necessary hardware for a seamless EFI upgrade. By packaging every element matched to the factory underbody layout, the system removes the risk of missing parts and cuts project planning time. Detailed installation instructions guide builders through each step, from mounting the tank to connecting the fuel lines and wiring the pump module. The comprehensive nature of this kit ensures a professional grade result without sourcing additional components or modifying the chassis. Whether you're building a weekend cruiser or a dedicated track car, the ready-to-install assembly simplifies the swap and delivers consistent fuel pressure for superior engine operation.
