EFI Fuel Tank Kit for 1970-1972 Chevelle LS and LT Swaps
When fitting an LS or LT engine into your 1970-1972 Chevelle A-Body, nothing matters more than consistent fuel flow and this EFI Fuel Tank Kit with its 400 LPH pump delivers exactly that. Custom engineered for classic Chevelle mounting points it installs with minimal fuss and offers a precise fit. Its advanced baffling system preserves steady delivery during hard cornering and supports more than 550 HP without risk of fuel starvation. Built in the USA with durable construction this kit ensures dependable performance for modern powerplants in vintage bodies.
Precision Mounting for 1970 to 1972 Chevelle A Body Frames
This fuel tank kit is custom engineered to match the original mounting points on 1970 to 1972 Chevelle A Body frames, eliminating the need for modification or trial fitting. Each mounting flange and bracket has been CAD modeled to factory dimensions so the tank seats flush and level, ensuring even load distribution under the rear of the chassis. By maintaining correct alignment with the body rails and filler neck, it preserves the Chevelle's factory look while supporting modern EFI hardware. The design also streamlines installation steps, reducing the time required to secure straps, gaskets and tank hardware to achieve a leak-free seal.
400 LPH Walbro Pump Capacity for High Output Engines
At the heart of this kit is a 400 liter per hour Walbro fuel pump designed to handle over 550 horsepower in forced induction setups. Its efficient internal impeller and high-pressure regulator deliver a constant stream of fuel even under sustained high RPMs, preventing lean conditions that can damage valves and pistons. This level of flow supports both LS or LT engine swaps, giving builders the confidence to pursue aggressive cam profiles and larger injectors without worrying about starvation. The pump's robust construction also tolerates variations in fuel temperature, maintaining consistent pressure across a wide range of operating conditions.
Tank Baffling System Ensuring Reliable Fuel Delivery
The kit's advanced baffling system creates multiple chambers inside the fuel tank to minimize slosh during cornering, acceleration and braking. By keeping the pickup tube submerged in fuel at all times, this internal maze prevents air from being drawn into the pump, which can trigger hard starts or intermittent misfires. The baffling walls are strategically positioned to dampen waves of liquid, preserving a stable supply even when the vehicle is subjected to track-style driving or spirited street use. This design ensures that fuel flow remains uninterrupted, protecting engine performance under the most demanding conditions.
Comprehensive Fuel System Components for Streamlined Assembly
Rather than sourcing parts from multiple vendors, this all-in-one kit includes every essential component needed for a complete fuel system upgrade. It bundles the 400 LPH pump, in-tank module, sending unit, filler neck, vent filter, tank straps, gaskets and mounting hardware. Each piece is matched to ensure perfect interoperability, eliminating common compatibility issues and reducing assembly time. Built in the United States from quality materials, these components work together to deliver a durable, serviceable installation that stands up to daily use and high-demand performance driving.
