EFI Fuel Tank Kit for 1968-1970 Pontiac GTO and Lemans LS Swaps
Whether you are fitting an LS powerplant into a 1968-1970 Pontiac GTO or Lemans A-Body, reliable fuel delivery starts with a precisely profiled tank. The 1968-1970 GTO / Lemans EFI Fuel Tank Kit combines a notched steel shell that provides full exhaust and tire clearance with an internal fuel pump module housing a 255 LPH Walbro pump capable of supporting builds up to 550 horsepower. This comprehensive kit also includes a sending unit, tank straps, filler neck, vent filter, gaskets and all necessary installation hardware. By aligning directly with original frame mounts, it installs without trimming and ensures compatibility with LS engine conversions for steady flow under hard acceleration and cornering.
Product Overview
The 1968-1970 GTO / Lemans EFI Fuel Tank Kit is engineered to deliver consistent fuel supply for drivers seeking modern drivability in classic A-body chassis. This assembly features a notched design to provide exhaust and tire clearance while maintaining chassis integrity. A high-performance 255 LPH Walbro pump is integrated to support engines up to 550 horsepower, ensuring precise delivery under high demand. The kit addresses fuel starvation concerns by maintaining steady fuel flow during spirited acceleration and cornering, delivering reliability in every driving condition.
Engineering Highlights
The tank's notched profile creates critical space for exhaust routing and rear wheel movement without requiring additional modifications. The in-tank pump module design maintains pump immersion even under heavy cornering forces, preventing fuel starvation. The 255 LPH pump offers a robust flow rate to meet the needs of performance LS powerplants, delivering enough volume for power levels up to 550 horsepower. This balance of volume and pressure control ensures fuel delivery remains consistent, reducing the risk of lean conditions during prolonged high-load operation on track or street.
Compatibility and Installation
Designed as a direct fit for 1968-1970 GTO and Lemans A-body chassis, the kit integrates seamlessly with existing mounting points and floor contours. It also supports LS engine conversions, guaranteeing accurate engine placement and correct drivetrain angles. The use of OE-style mounting hardware and gaskets simplifies installation and preserves chassis rigidity without the need for welding or fabrication. Each tank arrives notched and prepped for plug-and-play installation, allowing installers to focus on tuning and final fitment rather than custom clearance work.
Durability and Serviceability
Constructed from U.S. steel with a phosphate coating and quality sealants, the tank resists corrosion in diverse climates. A replaceable pump module allows quick service without removing the tank, and standard electrical connectors ensure straightforward wiring. The integrated fuel level sender uses OEM calibration, providing accurate gauge readings to eliminate guesswork. Routine maintenance and filter changes can be completed easily by accessing the service port, reducing downtime and preserving performance across the life of the vehicle.
Designed for LS engine conversions and direct fit into 1968 to 1970 Pontiac GTO and Lemans chassis, this tank offers notched clearance and a 255 LPH pump for steady delivery. To complete your Larger capacity fuel pump Kit at 400 LPH, consider our 1968-1970 GTO 400 LPH pump Tank Kit (notched).
