1965-1967 Pontiac GTO EFI Fuel Tank Kit with 400 LPH Pump for LS and LT Swaps
Integrating electronic fuel injection into your classic GTO can be complicated by outdated tank designs, but the 1965-1967 Pontiac GTO EFI Fuel Tank Kit - 400 LPH Pump delivers a tailored solution to support LS and LT swaps on an A Body chassis. Featuring a 400 LPH Walbro unit inside a custom tank, the kit maintains consistent flow even in boosted LS applications. All necessary straps, gaskets and vent filters are included to simplify assembly and preserve structural integrity under demanding conditions. American made and extensively tested, every component resists corrosion and handles fuel demands for engines pushing beyond 550 horsepower.
Precision Fit for 1965 to 1967 GTO A Body Chassis
This fuel tank kit is engineered to eliminate fitment challenges by matching the exact contours of the 1965 to 1967 Pontiac GTO, as well as compatible Lemans and Tempest models on the A Body platform. By tailoring mounting points and filler neck placement, it avoids the need for chassis modifications or custom brackets when installing LS or LT engines. The precision-fit design also ensures proper alignment of the in-tank components, reducing vibration and wear over time. This attention to detail means enthusiasts can focus on engine performance rather than wrestling with tank placement.
Steady Fuel Flow from 400 LPH Walbro Pump
At the heart of the assembly is a 400 LPH Walbro fuel pump that delivers a consistent supply of fuel under all driving conditions. Its capacity supports engines pushing beyond 550 horsepower, including boosted applications, by maintaining stable pressure and preventing starvation during cornering or hard acceleration. This level of flow control translates into smoother throttle response and reliable power delivery from idle to redline. The pump's in-tank location also helps to cool the motor, extending its service life.
All Inclusive Kit for Streamlined Assembly
Every necessary component is included to simplify your conversion, from the in-tank pump module and precise sending unit to heavy-duty tank straps, filler neck, vent filter, gaskets, and mounting hardware. This comprehensive package removes the guesswork and multiple sourcing trips that often delay custom fuel system builds. Each gasket and filter is chosen to maintain a tight seal and proper venting, preserving structural integrity and preventing fuel odors. Technicians and DIY enthusiasts alike benefit from a one-stop solution that makes installation faster and more reliable.
American Construction for Lasting Reliability
Manufactured in the United States, this fuel tank and pump kit undergoes stringent quality checks to meet demanding performance standards. The materials and components are selected for their resistance to corrosion and compatibility with modern fuels, ensuring that high horsepower applications can operate without compromise. Extensive testing under simulated driving conditions guarantees that the assembly withstands sustained use, from spirited street driving to track sessions. This commitment to domestic production and proven durability offers peace of mind for classic GTO owners seeking a dependable EFI solution.
