73-74 X-Body LS LT EFI Tank with 400 LPH Pump for Nova/Ventura/Apollo/Omega

Achieve reliable fuel support for over 550 hp LS and LT engines with the 1973-1974 Nova EFI Fuel Tank Kit that integrates a high-flow 400 LPH Walbro pump and precision mounts tailored for X-Body models. Complete with all necessary lines, fittings and a pressure regulator, this kit delivers smooth, responsive EFI performance and straightforward installation on Nova, Ventura, Apollo and Omega chassis.

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

If you’re installing an LS or LT engine into a 1973 to 1974 X Body project, the 1973-1974 Nova EFI Fuel Tank Kit - 400 LPH Pump provides the precise fuel pressure required to keep modern powerplants running smoothly. Matching factory mounts and filler neck alignment, it fits Chevy Nova, Pontiac Ventura, Buick Apollo and Oldsmobile Omega models without frame alterations. Because the internal 400 LPH Walbro module delivers stable flow for engines exceeding 550 horsepower, you can avoid lean conditions during sustained high rpm. Every module, seal and fitting ships preassembled for a straightforward installation and LS and LT compatibility from the moment you open the box.

Reliable Fuel Delivery for High Output LS and LT Engines

The internal 400 LPH Walbro pump maintains a consistent flow even under extended wide-open-throttle conditions, making it ideal for LS and LT powerplants above 550 hp. By being mounted inside the tank, the pump stays cool and shielded from road debris, which prevents vapor lock and minimizes cavitation under high-demand scenarios. This steady pressure delivery avoids lean spots that can cause detonation or accelerated wear on injectors and valves. Drivers gain confidence knowing the fuel system will support sustained high-rpm pulls without hiccups or pressure drop.

Precision Tank Integration on 1973 to 1974 X Body Models

This tank has been engineered to follow the original underbody contours of 1973 to 1974 Chevy Nova, Pontiac Ventura, Buick Apollo and Oldsmobile Omega, eliminating the need for frame modifications. Factory mounting locations and filler-neck alignment are preserved to ensure a seamless fit that maintains stock ground clearance and body lines. Internal bracing and reshaped baffles accommodate the EFI module while retaining the factory capacity, so owners don’t sacrifice range for modern performance. The result is a truly bolt-in solution that blends advanced technology with classic chassis geometry.

Comprehensive In Tank Kit for Effortless EFI Conversion

Every kit ships with a fully assembled fuel pump module, sending unit, tank straps, filler neck, vent filter, gaskets and all necessary hardware for a complete upgrade. Pre-plumbed and pre-wired components eliminate the need to hunt down adapters or fittings, speeding up installation and reducing potential leak points. Detailed instructions guide enthusiasts through each step, allowing those with basic mechanical experience to achieve professional results. With the entire system designed to work together from day one, converting a vintage X Body to modern EFI has never been more straightforward.

Count on precise fit and reliable EFI performance. For a smaller capacity fuel pump Kit at 255 LPH see our 1973-1974 Nova EFI Fuel Tank Kit - 255 LPH Pump.
