EFI Fuel Tank Kit with 255 LPH Pump for 1968-1969 Chevy Nova LS Engine Swap
Swapping an LS powerplant into a 1968 or 1969 Nova demands consistent fuel pressure to avoid hesitation under hard acceleration. This EFI Fuel Tank Kit bolts directly to factory mounts and arrives with a preassembled Walbro 255 LPH pump module complete with sending unit, filters and precisely formed steel shell that matches Nova chassis rails while internal vent channels guard against cavitation during tight cornering. In-tank placement reduces outlet temperatures and noise, sustains reliable flow for engines up to 550 horsepower and prevents lean spikes or vapor lock on spirited street or track runs.
In Tank Mounting for Cooler Fuel and Quieter Operation
Placing the pump inside the fuel reservoir shields it from engine bay heat, maintaining inlet temperatures at safer levels and reducing the risk of vapor lock during heavy throttle application. The surrounding volume of gasoline acts as a heat sink, drawing heat away from the pump body to preserve internal components and prolong operational life under sustained power demands. In addition, mechanical vibration and whine are absorbed by the steel walls and fluid medium, delivering a notably quieter cabin environment at idle and under full load. Consistent fuel temperature helps the ECU maintain precise injector pulse width calculations and supports uniform atomization across the rpm range. This temperature control and noise reduction ensure reliable fueling for LS swaps up to 550 horsepower, whether on a spirited street drive or occasional track outing.
Custom Steel Shell Geometry Matched to Nova Frame Rails
Engineered for the unique underbody contours of 1968 and 1969 Chevrolet Nova frames, the deep drawn steel shell features CNC formed flanges that align perfectly with factory mounting points. This direct match allows builders to retain original strap hardware and the stock filler neck cap, eliminating the need for cutting, welding or additional bracket fabrication. The tank profile is calibrated to preserve ground clearance and ensure the pickup remains submerged even under heavy acceleration, braking or lateral loads. Rubber strap mounts dampen vibration and prevent chafing against frame rails, while precision cut edges guard against leaks and ensure even gasket compression. With this tailored geometry, installers achieve a seamless fit that upholds the Nova's classic appearance while offering modern EFI reliability.
Fully Assembled Module Simplifies Installation Process
This comprehensive kit arrives with the Walbro 255 lph pump, sending unit, vent filter, gaskets and all necessary fasteners preinstalled in the tank shell. Precision molded seals around the module and sender ports reduce potential leak paths and guarantee correct alignment of hoses, electrical connections and the filler neck. Builders save significant time by avoiding separate sourcing of components and inline fittings, and the risk of part mismatch is eliminated from the outset. Grade A steel hardware is supplied to resist corrosion in a fuel environment, and tank straps are shaped to apply even tension for secure mounting. By combining every element into a ready to bolt in assembly, the installation steps are streamlined and post fit inspection is reduced to a quick systems check.
