1965-1967 Pontiac GTO A-Body EFI Fuel Tank Kit for LS and LT Engine Swaps
Putting a modern LS or LT mill into a mid 1960s GTO calls for a fuel supply you can count on. This 1965 to 1967 Pontiac GTO EFI Fuel Tank Kit with 400 LPH Pump blends a precision molded reservoir with a 400 LPH Walbro pump to sustain steady fueling under cornering or high load conditions. All mounting points follow the A Body floor pan layout and the kit arrives complete with straps gaskets and vent filters to save shop time and remove fitment headaches. Each component has endured ethanol resistance testing and corrosion checks to ensure reliability even in spirited runs or prolonged highway cruising.
Tailored Reservoir Design for 1965 to 1967 Pontiac GTO A Body
The fuel tank features a custom molded reservoir that matches the exact contours of the A Body floor pan in 1965 to 1967 Pontiac GTO models. By aligning with original mounting points, this design eliminates the need for custom brackets or alterations to frame rails. Secure seating reduces unwanted movement and vibration, which can compromise weld seams and internal components over time. Technicians benefit from a true drop in solution that maintains factory clearance, allowing attention to remain on engine performance rather than on fitment challenges.
Steady Fuel Delivery from 400 LPH Walbro Pump
At the heart of the kit is a 400 LPH Walbro pump engineered to sustain constant flow during cornering, hard acceleration, and sustained output beyond 550 horsepower. Placing the pump inside the tank ensures it remains submerged, delivering cooling from surrounding fuel and minimizing vapor lock risk. An integrated strainer keeps debris away from the inlet, extending service intervals and preserving output consistency. This level of delivery stability safeguards engine response in both naturally aspirated and boosted LS and LT configurations.
Unified Installation Kit for LS and LT Engine Swaps
This all inclusive package brings together every part needed for a seamless swap, from tank straps and gaskets to filler neck, vent filter, and calibrated sending unit. The sending unit is set to match the original gauge cluster, preserving accurate fuel level readings without extra adapters. Precision molded gaskets and filter elements prevent leaks and vapor odors, while all mounting hardware simplifies assembly. By sourcing each component in one shipment, builders avoid mismatched parts and wasted shop visits.
Advanced Ethanol and Corrosion Resistance in Premium Materials
Engineers selected materials tested for compatibility with modern ethanol blends and exposure to road salts, ensuring long term reliability. Each tank undergoes corrosion checks and endurance trials that mimic spirited street runs and extended highway use. Seals and welds are subjected to pressure cycles to confirm they remain leak free under real world conditions. Manufactured in the USA, the assembly meets strict quality standards, giving confidence that the fuel system will withstand demanding driving without degradation.
