LS EFI Fuel Tank Kit with 255 LPH Pump for 1968-1969 Chevy Nova
Starting an LS swap in a classic Chevy Nova often reveals the need for a dedicated EFI fuel system that can keep pace with modern injection demands. The 1968-1969 Nova EFI Fuel Tank Kit featuring a Walbro 255 LPH pump installs directly to your factory mounts and integrates a sending unit and precision steel shell shaped to chassis rails. By locating the pump inside the tank, it reduces inlet temperatures, cuts noise and locks out vapor formation under hard acceleration. This solution sustains reliable flow for builds up to 550 horsepower whether you're on street or track.
Pump Placement Inside Tank for Cooler Fuel and Noise Reduction
Positioning the Walbro 255 LPH pump within the steel reservoir lowers inlet temperatures by keeping the pump immersed in fuel, which acts as a heat sink. By reducing exposure to engine bay heat, the risk of vapor formation under heavy throttle is minimized, ensuring consistent pressure even during spirited driving. The surrounding liquid medium and tank walls also absorb mechanical vibration and drive noise away from the cabin environment. Cooler fuel temperatures contribute to steady injector calibration and uniform atomization across the rpm range, supporting LS engine performance up to 550 horsepower. This approach enhances reliability on both street and track applications.
Precision Formed Steel Shell for Direct Fit on 1968 and 1969 Chevy Nova Frame Rails
The deep drawn steel tank features flanges CNC formed to align precisely with the 1968 and 1969 Chevy Nova chassis rails, preserving the factory mounting geometry. Builders can retain original strap hardware and the stock filler neck cap without the need for cutting or welding modifications. The tank profile ensures the pickup remains submerged under hard acceleration, braking or cornering, preventing fuel starvation. Rubber mounting straps damp vibration and prevent chafing against frame components, while precision cut edges maintain even gasket compression to guard against leaks. This tailored design delivers a seamless integration that upholds the Nova's classic underbody lines.
Preassembled Module Streamlines Bolt-in Installation
This complete kit arrives with the pump, sending unit, vent filter, gaskets and hardware preinstalled into the tank shell, eliminating the need to source individual components. Precision molded seals around each port and the filler neck guarantee correct alignment of hoses, electrical connections and the fuel line. By combining every element into a ready to install assembly, builder error is minimized and setup time is cut significantly. Grade A steel hardware resists corrosion in a fuel environment, and pre shaped straps apply even tension for secure mounting. The result is a straightforward bolt-in solution that delivers reliable EFI operation for LS swaps in classic Novas.
