EFI Fuel Tank Kit for LS and LT Engine Swaps in 1970-1972 Chevy Chevelle
Engine swaps into a 1970-1972 Chevelle A Body hinge on a fuel tank that delivers consistent flow during cornering and hard launches; this EFI Fuel Tank Kit with a 400 LPH Walbro pump addresses that need. Its CAD designed flanges align perfectly with the factory rails to maintain correct body posture and streamline installation without trimming. The baffled interior keeps the pickup submerged to prevent air ingestion under sustained dynamic loads. Built in the United States from steel and corrosion resistant hardware, it combines pump, sending unit and mounting components into one integrated solution.
Precision Flanges Ensure Effortless Chevelle Tank Alignment
Each flange is the product of CAD modeling tailored to the 1970 to 1972 Chevelle A body rails, ensuring a perfect match with factory mounting points. This precise engineering eliminates the need for trimming sheet metal or performing trial fits, cutting installation time significantly. Maintaining the correct tank angle preserves the original filler neck orientation to prevent fuel leaks and retain the classic appearance. Even load distribution across the rear chassis keeps the tank stable under acceleration, cornering, and braking, so the unit remains flush against the body in every driving scenario.
Walbro 400 LPH Pump Maintains Consistent Delivery Over 550 HP
At the heart of this kit is a Walbro pump rated at 400 liters per hour, designed to support engine outputs above 550 horsepower without faltering. Its internal impeller geometry and built in regulator combine to deliver a steady flow that resists pressure drops at high rpm. This consistency reduces the risk of lean running during sustained wide-open throttle, safeguarding engine longevity. The pump also tolerates a wide range of fuel temperatures encountered in daily driving or track use, allowing builders to specify aggressive cam profiles or larger injectors with confidence.
Advanced Baffling Design Prevents Air Ingestion Under Dynamic Loads
Inside the tank, a network of baffle plates forms separate chambers that dampen liquid motion and keep the pickup fully submerged. This arrangement blocks air pockets from entering the fuel line during hard cornering, rapid acceleration, or sudden stops. By controlling wave patterns, the baffling system maintains continuous pressure at the outlet and prevents hesitation or misfire caused by momentary fuel starvation. The result is unwavering engine response whether you're navigating winding roads or launching off the line at the strip.
Comprehensive Kit Integration Simplifies Classic Chevelle EFI Upgrades
This all-in-one assembly unites the pump, in tank module, sending unit, straps, filler neck, vent filter, gaskets, and hardware into a factory-matched solution. Every piece works together to ensure seamless fitment and reduce the number of installation steps. Rather than sourcing parts from multiple suppliers, builders gain a unified package that eliminates compatibility questions and cuts overall assembly time. Constructed in the United States from robust steel and corrosion resistant fittings, the kit delivers reliable service and straightforward maintenance in a classic Chevelle body.
