LS Fuel Tank Kit with 255 LPH Pump for 1965-1967 Pontiac GTO
When converting your classic A body to LS power, factory tanks often suffer fuel starvation under sustained cornering or rapid throttle transitions. The 1965 to 1967 Pontiac GTO EFI Fuel Tank Kit with 255 LPH Pump steps in with an OEM style steel reservoir and a Walbro tank mounted module that delivers 255 liters per hour while maintaining engineered baffling to keep the pump submerged at all times. This USA assembled system integrates directly using original mount points and includes all hardware from straps and vent filter to filler neck and gaskets. A calibrated sending unit preserves factory gauge accuracy and the module will reliably support up to 550 horsepower without modification, offering a straightforward solution for LS engine swaps in 1965-1967 GTO models and 1966-1967 LeMans and Tempest models.
Comprehensive EFI Conversion Kit
Our fuel tank kit is engineered specifically for 1965-1967 Pontiac GTO models and 1966-1967 LeMans and Tempest models. Designed for modern LS engine installations, the system includes a robust 255 LPH high-flow pump from Walbro, delivering consistent supply for up to 550 HP output. Every component aligns with original body dimensions so there is no need for cutting or welding. By maintaining precise geometry, the module integrates seamlessly with factory mounting points to preserve chassis integrity and streamline installation time.
Precision Fuel Management
At the core of the system is the precision fuel sending unit that delivers factory gauge performance. This ensures that fuel level readings match those of the stock instrument cluster. Inside the tank, engineered baffling prevents fuel migration during acceleration, cornering, or braking, safeguarding constant pickup even under heavy use on road or track. This design eliminates typical issues such as vapor lock or fuel starvation that can occur in unmodified reservoirs, enabling maintainable and reliable operation under all driving conditions.
Direct Integration and Quality Assurance
The entire assembly is proudly made in the USA to meet strict quality standards. Components are manufactured to OEM tolerances, yielding direct fitment without the need for alterations. Since no modifications are required for installation, body panels and frame elements remain untouched, reducing labor costs and preserving vehicle value. The tank is compatible with MuscleRods control arm mounts when used in LS engine swap configurations, ensuring that drivetrain angles remain optimized and alignment is maintained without additional shims or adapters. Each kit undergoes rigorous flow tests and leak checks before shipping, guaranteeing that it arrives ready for immediate use.
Durability and Material Selection
This tank is fabricated from high grade steel and finished with epoxy to resist corrosion over time. Strategic seam welding provides structural integrity capable of withstanding road vibrations and stress common to classic muscle car use. The scratch resistant topcoat allows removal and reinstall without compromising the protective layer so the unit maintains visual consistency in show or daily driving scenarios. Fuel resistant seals and O rings are selected for ethanol blend compatibility, safeguarding against degradation and ensuring years of trouble free operation.
