LS and LT Engine Swap Fuel Tank Kit for 1970-1972 Chevy Chevelle
When your build involves swapping an LS or LT engine into a 1970 to 1972 Chevelle, consistent fuel delivery becomes critical. This EFI Fuel Tank Kit for 1970 to 1972 Chevelles features a 400 LPH Walbro fuel pump and a baffled interior to keep injectors fed even under sustained cornering and spirited acceleration. Its precision mounting flanges align with the original body rails to ensure straightforward installation and maintain proper strain distribution across the rear chassis. Built in the United States from steel and corrosion resistant hardware, this kit integrates the pump, sending unit and mounting components into a self contained solution that eliminates guesswork when fitting modern EFI gear into classic sheetmetal.
Precise Chevelle Frame Fitment
Each EFI fuel tank is CAD modeled to match the original mounting points on 1970 to 1972 Chevelle frames, ensuring a secure and level installation without any trimming or trial fitting. By aligning the flanges and brackets exactly with factory body rails, the design distributes load evenly across the rear chassis and preserves the car's classic proportions. This precise fit also maintains the correct angle of the filler neck to guard against leaks and to retain the stock appearance. The result is a hassle free mounting process that keeps the tank seated flush and stable under all driving conditions.
400 LPH Walbro Pump Supporting Over 550 HP
At the core of this kit is a 400 liter per hour Walbro pump engineered to deliver uninterrupted flow for engines exceeding 550 horsepower. Its efficient impeller design and integrated pressure regulator maintain consistent output even at high RPM and under boost, preventing lean conditions that can lead to engine damage. The pump also tolerates wide swings in fuel temperature, so performance remains steady whether on a hot track or during extended street use. Builders can confidently choose aggressive cams and larger injectors without concern for supply limitations.
Advanced Tank Baffling System for Stable Delivery
The internal baffling creates a series of chambers within the tank to minimize fuel movement during cornering, hard acceleration, and sudden stops. By keeping the pickup tube fully submerged, the design prevents air from entering the fuel line and eliminates pulse related misfires or hard starts. Strategic placement of baffle walls dampens waves of liquid, preserving a steady supply under spirited driving or on the track. This engineered control of fuel slosh ensures the engine receives an uninterrupted flow in every situation.
Complete Fuel System Kit for Simplified Assembly
Rather than sourcing parts from multiple suppliers, this all in one solution includes the pump, in tank module, sending unit, filler neck, vent filter, straps, gaskets and hardware. Each component is factory matched for seamless compatibility, cutting out common fitment headaches and reducing assembly time. Manufactured in the United States from robust steel and corrosion resistant hardware, the kit delivers durable performance and easy service access. As a unified package, it streamlines the upgrade to modern EFI in a classic Chevelle body.
