1970 Chevy Nova 400 LPH EFI Fuel Tank Kit for LS and LT Swaps
An LS or LT engine swap in a 1970 Chevy Nova requires a fuel tank that both fits the original underbody and delivers enough fuel for boosted or high horsepower setups. By retaining the stock tank footprint, the 1970 Nova EFI Fuel Tank Kit with its 400 LPH pump slips into factory mounting points without frame modifications. Its integrated fuel pressure regulator and vent filter hold system pressure steady under load while the factory grade sending unit ensures accurate level readings. Stainless steel construction with AN fittings resists corrosion and vibration so flow remains consistent during extended full throttle runs.
Precision Fit Maintains Stock Footprint and Mounting Geometry
The tank retains the original 1970 Chevy Nova underbody shape to eliminate custom frame work or filler neck relocation. By using factory mounting points and the OE filler position installers can lower in the new module without altering chassis components. This exacting alignment reduces setup time and ensures consistent strap tension so the tank remains secure under varying loads. Maintaining stock geometry also preserves ride height and prevents interference with exhaust or suspension parts. As a result builders gain confidence that fuel delivery integration will not compromise the classic Nova appearance or handling.
400 LPH Walbro Pump Performance for LS and LT Engine Swaps
At the heart of this kit lies a 400 LPH Walbro pump rated for supercharged and engines over 550 hp, supplying the volume required by boosted and high output powerplants. Placing the pump inside the tank module leverages efficient suction that minimizes cavitation during rapid throttle changes. Internal installation also reduces noise and heat buildup by routing fuel directly from the reservoir rather than through long feed and return lines. This design ensures consistent pressure at the rail even during hard launches or track sessions and helps prevent fuel starvation under sustained demand. The pump feed profile is optimized for EFI systems so injection timing and mixture remain stable across the rev range.
Integrated Pressure Regulation and Vent Filtration for Stable Operation
The built in fuel pressure regulator holds system pressure within a narrow window, allowing precise tuning of air fuel ratios without concern for pressure spikes or drops. Combining regulation with an onboard vent filter removes debris and separates vapor from liquid fuel, reducing the chance of vapor lock in hot or heavy load conditions. This dual function assembly cuts out extra plumbing and hose connections, shrinking potential leak points and simplifying the overall plumbing layout. The result is smoother throttle response and reliable fuel delivery whether driving on the street or racing on the strip. Tuners appreciate the consistent baseline pressure when dialing in advanced engine maps.
Stainless Steel Construction Paired with AN Fittings for Long Term Durability
The tank body is crafted from corrosion resistant stainless steel that withstands ethanol blends, road salts and temperature extremes without pitting or metal fatigue. Precision machined AN ports and robust stainless steel hardware deliver leak resistant connections that tolerate vibration and thermal cycles inherent to performance driving. By avoiding stamped sheet steel the assembly resists deformation and maintains its form over many seasons of use. All gaskets and mounting straps are supplied to ensure a complete seal and proper alignment at installation. This durable combination keeps maintenance to a minimum and protects the fuel system investment throughout the life of the vehicle.
Built for lasting reliability and precise fit, this kit ensures steady fuel delivery under varied conditions. To match a smaller capacity fuel pump kit at 255 LPH consider our 1970 Nova EFI Fuel Tank Kit - 255 LPH Pump.
