LS and LT EFI Fuel Tank Kit for 1970 Chevy Nova with 400 LPH Pump
Beginning your LS or LT engine swap in a 1970 Chevy Nova demands a tank that retains the classic underbody shape while supplying high volume for boosted or 550 plus horsepower setups. The 1970 Nova EFI Fuel Tank Kit with 400 LPH Pump installs a 400 LPH pump into a stainless steel reservoir designed for direct fit on factory mounts, eliminating frame alterations. Integrated pressure regulation, a vent filter and a sending unit together hold system pressure steady and ensure precise fuel-level readings during spirited driving. Each AN fitting and durable wall thickness resists corrosion and vibration, so fuel flow remains consistent whether cruising the street or pushing limits on the strip.
Precision Fit for Classic 1970 Nova Underbody
This fuel tank kit replicates the original 1970 Chevy Nova underbody shape to eliminate any need for chassis alterations. By matching factory mounting points and maintaining the OE filler neck position, installers can drop the module into place without cutting or welding. This precise alignment preserves strap tension and prevents rattles or shifting during spirited driving. Builders benefit from a drop in replacement that safeguards ride height, suspension clearance and the vehicle's timeless stance.
In tank 400 LPH Walbro Pump Delivers Consistent Volume
At the core of this assembly is a 400 LPH Walbro pump engineered to supply the fuel demands of boosted LS or LT powerplants and engines above 550 horsepower. Housing the pump inside the reservoir taps the most efficient suction zone and reduces the risk of cavitation during rapid throttle transitions. This internal location also dampens vibration and noise while shortening feed lines to the EFI system for smoother response. The result is stable rail pressure that supports precise injection timing across all driving conditions.
Integrated Pressure Regulator and Vent Filtration for System Stability
This module features a built in pressure regulator that holds fuel rail pressure within a tight window, enabling accurate tuning and preventing lean or rich spikes during acceleration. Paired with an onboard vent filter, it screens out debris and separates vapor from liquid fuel to guard against vapor lock in extreme heat or heavy load scenarios. Combining regulation and filtration in a single unit reduces external hoses and fittings, minimizing potential leak points and simplifying the plumbing layout. Tuners appreciate the clean, predictable baseline pressure when refining engine calibration.
Stainless Steel Construction with AN Fittings for Lasting Durability
The tank body is formed from corrosion resistant stainless steel that stands up to ethanol blends, road salt and temperature cycles without pitting or fatigue. Precision machined AN ports and stainless steel hardware deliver secure, leak resistant connections that endure the vibration and thermal expansion of performance driving. By avoiding stamped sheet steel, the assembly retains its shape season after season and resists dents or deformation. Complete with gaskets, mounting straps and filler neck hardware, this kit ensures a tight seal and dependable operation over the life of the conversion.
