1973-1974 Nova, Ventura, Apollo, Omega X-Body Fuel Tank

Maintaining stable fuel delivery for engines exceeding 550 hp, the 1973-1974 Nova EFI Fuel Tank Kit combines a 400 LPH Walbro pump with tailored mounts for seamless LS and LT conversion in your X-Body car. Complete with all necessary lines, fittings and a pressure regulator, it delivers smooth, responsive EFI performance and hassle free installation with drop in fitment.

1973-1974 X-Body LS and LT EFI Fuel Tank Kit with 400 LPH Pump

When swapping an LS or LT powerplant into a classic Nova, the 1973-1974 Nova EFI Fuel Tank Kit - 400 LPH Pump delivers the precise fuel pressure needed for reliable operation. It fits Chevy Nova, Ventura, Apollo and Omega models from 1973 and 1974 without any frame modifications. The internal 400 LPH Walbro unit maintains stable flow for engines exceeding 550 horsepower. Every fitting, seal and module ships preassembled so you gain LS and LT compatibility from the moment you open the box.

Precision Fuel Delivery for High Horsepower LS and LT Engines

The 400 LPH Walbro pump provides a steadfast flow rate ideal for engines producing over 550 horsepower. Placed inside the tank, this design maintains consistent delivery even under wide-open throttle and sustained high-rpm operation. By keeping fuel pressure steady, it prevents lean conditions that can lead to detonation or component wear. This level of control is essential when modern LS and LT powerplants demand precise fueling in a vintage chassis.

Vehicle Specific Tank Design for 1973 to 1974 X Body Models

This fuel tank is shaped to match the original contours of Chevy Nova, Ventura, Apollo and Omega models without frame alterations. Factory mounting points and filler neck alignment remain unchanged, so installation is straightforward and retains the vehicle's stock appearance. Internal modifications accommodate the in-tank module and sending unit while preserving original capacity. The result is a near-factory fit that integrates modern EFI hardware with classic underbody geometry.

Complete In Tank Conversion Kit Simplifies EFI Integration

This all in one installation package includes a Walbro fuel pump module, sending unit, tank straps, filler neck, vent filter, gaskets and all required hardware. Having every component preassembled and ready to install removes the need to source separate fittings or adapters, saving time during your conversion. The in-tank module arrives wired and plumbed for direct connection to factory lines, ensuring correct pressure regulation without additional modifications. Even the vent filter and gaskets are chosen to match the original X body specifications, creating a leak-free system from day one. With detailed instructions, enthusiasts with basic mechanical skills can complete the swap without altering the frame or body.

Count on consistent performance in lower flow applications. To complete your smaller capacity fuel pump Kit at 255 LPH Pump, see our 1973-1974 Nova EFI Fuel Tank Kit - 255 LPH Pump.
