LS and LT EFI Fuel Tank Kit for 1971-1972 Pontiac GTO and Lemans
This EFI fuel tank kit solves fuel starvation and fitment conflicts when swapping LS or LT engines into 1971 to 1972 Pontiac GTO and Lemans models. Featuring a precision welded steel reservoir notched to clear exhaust routing and rear tire paths without altering factory frame rails. Protected inside, a 400 liters per hour pump and integrated sending unit maintain stable flow and accurate level feedback under sustained throttle while a fine mesh filter prevents vapor lock. With all brackets straps and adapter fittings included, installation bolts on to stock rails in minutes without cutting or welding, delivering a ready made EFI foundation for high output LS and LT power delivery.
Precision Notched Reservoir Design for Seamless Frame Compatibility
The notched steel tank is shaped to follow the underbody contours of early seventies GTO and Lemans chassis. By removing material only where exhaust pipes or tire arcs pass, the design maintains original rail strength and eliminates interference. This approach lets installers bolt the reservoir in place without cutting or welding. The exact fit also reduces alignment checks, making fuel system integration predictable during an LS or LT swap.
400 LPH Walbro Pump Ensures Stable Flow for High Output Engines
The heart of this kit is a 400 liters per hour Walbro pump that handles heavy demand from modern LS or LT powerplants. It sustains precise flow under sustained full throttle, avoiding lean runs that damage engine components. Internal vanes resist cavitation at high rpm while the robust housing handles heat under constant load. Drivers benefit from consistent pressure whether idling in traffic or pushing hard on track circuits.
Integrated In Tank Module Delivers Reliable Level Feedback
This integrated in tank module unites the pump, sending unit and fine mesh vent filter in one sealed assembly. The calibrated float arm delivers accurate level feedback even under hard acceleration or tight cornering, eliminating erratic gauge readings. Smooth internal flow paths and reduced dead volume keep the pump submerged, lowering wear over time. Factory style connectors fit without modification and block moisture to ensure reliable performance.
Complete Bolt In Hardware Kit Streamlines EFI Retrofit
All necessary brackets, straps, gaskets and adapter fittings arrive ready to bolt onto the original frame rails. Pre shaped tank straps cradle the steel reservoir for secure support and the filler neck adapter aligns precisely with the stock opening. Matching vents and hardware mirror factory dimensions, so no custom parts hunting is required. This complete bolt in package cuts installation time and reduces the risk of leaks or misalignment.
