1970 Chevy Nova LS and LT EFI Fuel Tank Kit with 400 LPH Pump
Tackling a high output LS or LT engine swap in a 1970 Chevy Nova often hinges on reliable refueling under every driving scenario. The 1970 Nova EFI Fuel Tank Kit - 400 LPH Pump installs neatly on the stock mounts and preserves the classic underbody contour while delivering sustained volume for boosted or 550 hp plus powerplants. Featuring a genuine Walbro 400 LPH pump housed inside a stainless steel reservoir, the kit taps the best suction zone to reduce feed line length and guard against cavitation during rapid throttle transitions. An integrated pressure regulator, vent filter and precision sending unit hold fuel pressure uniform and provide accurate level readings whether cruising or tackling the strip. Precision machined AN fittings and a durable wall thickness stand up to corrosion and vibration so fuel flow stays consistent in everyday driving and high demand conditions.
Factory Fitment for Original Nova Underbody
This fuel tank kit is engineered to match the 1970 Chevy Nova underbody contour so installers can drop it into place using existing frame mounts and the original filler neck location. By aligning with factory strap points and preserving ride height and suspension clearance, it eliminates the need for any cutting, welding, or frame modifications. Maintaining the stock profile also ensures the chassis retains its classic stance and reduces installation time. Builders benefit from a plug and play solution that safeguards vehicle geometry and underbody appearance while supporting modern LS or LT powerplants.
Reservoir Mounted Walbro Pump for Improved Suction
At the heart of this assembly sits a genuine 400 LPH Walbro fuel pump positioned inside the stainless steel tank to tap the optimal suction zone. This internal placement shortens feed lines and reduces the risk of cavitation during rapid throttle transitions, delivering consistent volume for supercharged and 550 hp applications. Housing the pump within the reservoir also dampens vibration and sound, resulting in a quieter fuel system operation. The direct connection to the EFI rails ensures steady pressure and rapid response even under heavy load.
Combined Regulator and Vent Filter for Stable Pressure
The integrated fuel pressure regulator holds rail pressure within a precise window, preventing lean or rich spikes during acceleration or quick throttle changes. Paired with an onboard vent filter, the module screens out debris and separates vapor from liquid fuel to protect against vapor lock in hot conditions or under heavy engine load. By combining these functions into a single unit, the design reduces external lines and fittings, minimizing potential leak points and simplifying plumbing. Tuners gain a reliable baseline for fine tuning injection timing and engine calibration.
Stainless Steel Tank and AN Fittings for Long Term Durability
Constructed from corrosion resistant stainless steel, the fuel tank withstands ethanol blends, road salt, and thermal cycling without pitting or deformation. Precision machined AN ports and stainless hardware deliver leak resistant connections that handle the vibration and expansion of performance driving. Unlike stamped panels, this thicker wall construction resists dents and retains its shape season after season. Included mounting straps, gaskets, and filler neck hardware complete the assembly for a secure seal and dependable operation throughout the life of an LS or LT conversion.
