1965-1967 Pontiac GTO EFI Fuel Tank Kit for LS and LT Engine Swaps
Tackling an LS or LT swap in a classic GTO often comes down to finding a fuel tank that matches the car's contours while feeding a performance engine. Designed for A Body applications the kit pairs a custom-molded reservoir with a 400 LPH Walbro pump to deliver steady flow for boosted LS and LT builds. Including all required straps, gaskets and vent filters streamlines installation and maintains corrosion resistance during spirited driving. Engineers have tested each element to handle more than 550 horsepower without requiring frame rail or filler neck modifications.
Engineered Fit for 1965 to 1967 GTO A Body Chassis
Every contour and mounting point is tailored to the original floor pan of a 1965 to 1967 Pontiac GTO, along with select LeMans and Tempest models sharing the A Body architecture. This precision alignment eliminates the need for custom brackets or frame rail alterations during an LS or LT swap. Proper seating of the tank reduces movement and vibration, preserving the integrity of both the reservoir and in-tank components over thousands of miles. Technicians will appreciate the drop-in nature of this design, which keeps focus on performance rather than fitment challenges.
Consistent Supply from 400 LPH Walbro Pump
At its core, the kit features a 400 LPH Walbro unit engineered to maintain a steady fuel flow even under cornering, hard acceleration, or when running more than 550 horsepower. By locating the pump inside the tank, the system benefits from constant fuel cooling and reduced vapor formation that can lead to hesitation. The robust internal strainer and integrated module ensure debris stays clear of the pump inlet, contributing to prolonged service life. For boosted LS and LT configurations, this level of delivery safeguards against momentary starve that can compromise engine response.
Complete Kit for Streamlined Installation
This package combines every essential element needed for a seamless swap, including the fuel pump assembly, sending unit, heavy-duty straps, filler neck, vent filter, gaskets, and mounting hardware. The sending unit is calibrated to work with the original gauge cluster, preserving accurate fuel level monitoring without additional adapters. Vent filters and precision-molded gaskets prevent leaks and vapor odors, while included straps and hardware secure the tank firmly in place. By sourcing all items in one shipment, installers avoid delays and mismatched parts that often arise during custom builds.
American Craftsmanship Ensures Durability for Powerful Builds
Manufactured in the USA, this tank and pump kit undergo rigorous quality checks to meet demanding driving conditions from spirited street runs to track days. Materials are selected for their resistance to ethanol blends and corrosion, providing a reliable foundation for years of use. Endurance testing simulates slalom courses, bumps, and extended high-load operation to confirm that seals and welds remain leak-free. This commitment to domestic production and proven durability delivers confidence that your fuel system will keep pace with any LS or LT engine upgrade.
