1968-1969 Chevy Nova EFI Fuel Tank Kit for LS Swaps with 255 LPH Pump
An LS powerplant in a 1968-1969 Chevy Nova requires a fuel tank that can maintain constant pressure during spirited driving and heavy acceleration. This 1968-1969 Nova EFI Fuel Tank Kit with a 255 LPH pump installs on factory mounting points and delivers reliable flow for builds up to 550 horsepower. Engineers have preassembled the Walbro module inside the tank with a sending unit, filters, and all mounting hardware to remove the guesswork from installation. Integrated venting balances internal pressure as fuel level changes to prevent cavitation under cornering or sudden throttle lifts, keeping the EFI system response consistent.
Precision Fuel Delivery with Walbro Pump
The in-tank Walbro 255 LPH pump is calibrated to sustain a steady flow rate for LS engines producing up to 550 hp. Installing the pump inside the shell minimises exposure to heat and reduces operational noise, enhancing longevity and driver comfort. This precise fuel delivery prevents starved injectors during hard acceleration and aggressive cornering, which in turn improves atomisation and throttle response. By maintaining a stable supply, the system ensures the engine control unit can adapt quickly to dynamic load changes without lean spikes or hesitation.
Exact Fitment to 1968 to 1969 Nova Frames
Every tank is CNC formed to match the factory mounting points of 1968 and 1969 Chevy Nova chassis, so there is no need for custom brackets or welding. The filler neck aligns perfectly with the original opening, preserving the vehicle's classic appearance while allowing use of the stock cap. Rubber strap mounts isolate vibration and prevent chafing against the frame rails, while precision-cut flanges guarantee even load distribution. Builders can focus on tuning rather than cutting or modifying metal.
Engineered Vent Path for Consistent Pressure Control
An integrated vent channel in the tank shell balances internal and external pressure as fuel levels fluctuate during spirited driving. This engineered airflow path prevents the creation of vacuum pockets that could hinder pump performance or cause cavitation under lateral G forces. Consistent venting supports uninterrupted fuel flow in high-G cornering and sudden throttle lifts, preserving stable fuel trims. As a result, fuel pressure remains within optimal range across varied driving conditions.
Cohesive Module Assembly Streamlines Setup
The kit arrives fully assembled with the pump module, sending unit, vent filter, seals and all necessary hardware preinstalled inside the tank. This cohesive construction eliminates parts mismatch and simplifies alignment of wiring and hoses. Precision molded seals around the pump and sender keep the system leak free under vibration and temperature cycling. With everything in place, installation time shrinks and post-install adjustments become minimal, allowing builders to complete their swap more efficiently.
