1971-1972 Chevy El Camino LS and LT Engine Swap Fuel Tank Kit
When installing an LS or LT powerplant in an early A Body El Camino from 1971 and 1972, this fuel tank kit solves chassis clearance issues and fuel starvation under heavy load with upgraded flow and a precision notch in the tank body. It features a 400 LPH Walbro pump integrated into a tank body shaped to clear exhaust paths and rear tire travel on the A Body frame without trimming sheet metal. Plug in GM style wiring and American made straps and gaskets simplify installation and ensure steady delivery during turbocharged or supercharged runs.
Pump Performance at 400 LPH
The 400 LPH Walbro pump in this kit is sized to meet the demands of supercharged and high output LS or LT engines that push beyond 550 horsepower. Its design resists heat soak and voltage issues under sustained load, ensuring a steady flow of fuel during full throttle acceleration. That consistent supply helps prevent lean conditions and protects against detonation, which is critical for forced induction. The extra capacity also leaves room for future power upgrades, so you will not need an early replacement. Technicians value its durable internals that support both track days and tough street use.
Tank Notch Design for Chassis Clearance
The precision notch in the tank body is engineered to clear exhaust pipes and rear tire travel on the early El Camino frame without any cutting of sheet metal. By matching the contour of the A Body chassis, the profile preserves suspension geometry and ride height under load. Installers can simply lower the unit into the original strap mounts, avoiding time consuming fitment work. The design also maintains balanced weight distribution, ensuring handling remains predictable during hard cornering. This feature eliminates the risk of contact, even when ride height is lowered.
Seamless Module Integration with GM Wiring
This kit's pre assembled in tank fuel pump module plugs directly into existing GM style wiring and stock fuel rail fittings without any adapter harnesses. The sending unit and pump are aligned to the original filler neck and strap positions, so the tank seats securely and precisely on the chassis. That direct compatibility cuts installation time by removing the need for splices, filler neck modifications, or special tools. Even installers new to LS or LT swaps can complete plumbing and wiring without troubleshooting fit issues. The result is a clean and reliable connection for consistent fuel delivery.
American Made Hardware for Lasting Durability
All straps, fittings, gaskets, and vent filters in this fuel tank kit are manufactured in the United States to high standards for corrosion resistance and vibration tolerance. Stainless steel straps retain strength under chassis movement and resist rust over time. Precision machined filler necks ensure a leak free seal and gaskets withstand fuel additives and temperature changes. The vent filter helps keep debris from entering the system, protecting the pump and downstream components. This domestic heritage of quality parts delivers reliable service in both street and racing conditions.
