EFI Fuel Tank Kit for 1971-1972 Pontiac GTO and Lemans LS and LT Swaps
Installing an LS or LT engine in a 1971 to 1972 Pontiac GTO or Lemans often runs into fuel starvation because the original tank cannot support modern injectors. This EFI fuel tank kit features a notched steel reservoir to clear exhaust routing and wheel wells while preserving frame rail integrity. It houses a 400 liters per hour pump with integrated sending unit and vent filter for accurate level feedback under sustained throttle. All required brackets, straps and adapter fittings bolt on without cutting or welding to complete the fuel system upgrade quickly.
Precision Notched Steel Reservoir for Exhaust and Tire Clearance
The custom notched profile of the fuel tank is engineered to follow the original frame rail contours of early seventies Pontiac GTO and Lemans models. By trimming only where clearance is required, the design avoids interference with exhaust piping and rear wheel movement while preserving factory underbody strength. This close adherence to chassis geometry means installers can position the tank without reshaping rails or welding brackets. Technicians report that the exact fit slashes alignment checks and trial fitting, making the swap process more predictable and eliminating costly frame modifications.
400 LPH Walbro Pump Sustains 550 HP Engine Requirements
At the heart of this kit is a 400 liters per hour fuel pump proven to keep pace with high-output LS and LT powerplants exceeding 550 horsepower. Maintaining a stable flow under wide open throttle prevents lean conditions that can cause detonation or piston damage. The pump's internal design resists cavitation at sustained high rpm and endures prolonged operation without overheating. As a result, drivers can trust consistent delivery whether cruising on the highway or pushing hard on the autocross course.
Integrated In-Tank Module for Accurate Level Sensing and Slosh Control
This combined unit houses the pump, sending unit and fine mesh vent filter in one compact assembly. The calibrated float arm delivers precise fuel level feedback even during hard acceleration or sharp cornering, eliminating erratic gauge readings common in retrofit systems. Internally, the smooth module shape and minimized dead head volume help keep the pump constantly submerged, extending its service life. Factory style electrical connectors seal against moisture and simplify wiring, so installers enjoy a clean fit with minimal sealant or extra fittings required.
Complete Bolt In Kit Streamlines Fuel System Retrofit
Every bracket, strap, filter and adapter needed for an EFI conversion arrives ready to mount on stock frame rails. Tank straps are pre shaped to cradle the reservoir, while the filler neck adapter aligns perfectly with the original housing. Vent lines, gaskets and hardware match factory dimensions for a leak free assembly without searching for specialty parts. This ready made solution reduces downtime, cuts back on parts juggling and ensures a cohesive system where each component is validated to work seamlessly with the others.
Install with confidence knowing every component meets factory standards. To complete your Smaller capacity fuel pump Kit at 255 LPH consider our 1971-1972 GTO 255 LPH pump Tank Kit (notched).
