400 LPH Fuel Tank Kit for 73-74 X-Body LS LT

Engineered with a high volume 400 LPH Walbro pump and precision mounts, the 1973-1974 Nova EFI Fuel Tank Kit ensures stable fuel delivery above 550 horsepower for a seamless LS or LT conversion on X Body chassis. Outfitted with all required lines, fittings and a pressure regulator, this turnkey solution delivers smooth, responsive EFI support and drop in fitment for Chevy Nova, Pontiac Ventura, Buick Apollo and Oldsmobile Omega models for reliable performance.

LS and LT EFI Fuel Tank Kit for 1973-1974 X-Body Nova/Ventura/Apollo/Omega

When an LS or LT engine swap calls for reliable fuel pressure on a classic Nova or similar X Body platform, the EFI tank kit with a 400 LPH pump ensures precise underbody fit while preserving factory mounting points. It follows original tank contours for 1973 to 1974 Chevy Nova, Pontiac Ventura, Buick Apollo and Oldsmobile Omega, dropping in without altering undercarriage geometry or ground clearance. The in tank Walbro module stays cool and protected from road debris, delivering stable flow for setups exceeding 550 horsepower and reducing the risk of lean spots during sustained high rpm runs. Every seal fitting and pressure regulator arrive pre assembled so enthusiasts can install the complete system quickly and enjoy consistent EFI performance out of the box.

Precision Matched Fuel Delivery for Engines Exceeding 550 HP

The 400 LPH Walbro pump module inside this EFI tank kit delivers a consistent supply of fuel under sustained high-rpm operation. By maintaining stable pressure, it prevents lean spots that can lead to detonation or premature wear on injectors and valvetrain components. This precision matched flow supports engines above 550 horsepower without fluctuations, ensuring smooth throttle response during spirited driving or track sessions. Enthusiasts benefit from predictable performance, knowing the fuel system will keep pace with aggressive power demands.

In-Tank Pump Cooling and Protection

Submerging the fuel pump within the tank harnesses the liquid itself as a coolant, avoiding heat-related performance loss and extending component life. It also shields the module from road debris, reducing the chance of damage and minimizing pump cavitation under heavy load. This enclosed design prevents vapor lock, even during steep climbs or extended wide-open throttle runs. The result is reliable operation and peace of mind for daily driving or high-stress racing conditions.

Factory Style Fitment Maintains Original Underbody Geometry

The tank's contours precisely follow the floorpan of 1973 to 1974 Chevy Nova, Pontiac Ventura, Buick Apollo and Oldsmobile Omega models, preserving ground clearance and body lines. Retaining stock mounting brackets and filler-neck alignment means no cutting or bending of the frame rails is required for installation. Internal baffles have been reshaped to accommodate the EFI module while keeping full fuel capacity and preventing slosh during cornering. Owners enjoy a bolt-in retrofit that supports modern engine swaps without compromising the classic chassis layout.

Integrated Kit Components Streamline Installation

Every seal, fitting and regulator arrives preassembled, eliminating the need to source separate adapters or hunt down specialized hardware. The kit includes the Walbro module, sending unit, tank straps, filler neck, vent filter, gaskets and all necessary fasteners to complete the conversion in one go. Detailed, step-by-step instructions guide installers through each stage, reducing potential leak paths and ensuring a professional-quality result. Even builders with modest mechanical experience can achieve a durable, fully functional EFI system in minimal time.

Count on reliable pressure delivery in your swap. For a Smaller capacity fuel pump Kit at 255 LPH see our 1973-1974 Nova EFI Fuel Tank Kit - 255 LPH Pump.
