1968-1970 Pontiac GTO/Lemans A-Body LS and LT EFI Fuel Tank Kit
When adapting an LS or LT engine into a 1968-1970 A-Body GTO or Lemans, the 1968-1970 GTO / Lemans EFI Fuel Tank Kit equipped with a 400 LPH Pump addresses both underbody clearance challenges and high capacity demands with precision. Constructed from heavy gauge steel, its notched tank profile carves clearance for header pipes and rear suspension components without compromising structural integrity. A submerged Walbro pump delivers a reliable 400 liters per hour of fuel flow, reducing heat soak and cavitation under sustained load. Technicians benefit from a complete hardware package that matches original mounting points and streamlines the swap process while maintaining accurate fuel level readings.
Precision Notched Profile for Exhaust and Suspension Clearance
The notched tank design carves out dedicated pockets to clear header pipes and rear suspension components on 1968 to 1970 A Body chassis. By maintaining a consistent wall thickness around each cutout, this profile minimizes heat soak and prevents vapor lock during spirited driving or track duty. Installers benefit from a streamlined fitment process that removes the need for custom metal trimming and ensures proper alignment at factory ride height. The heavy gauge steel construction maintains structural rigidity even with aggressive cornering forces, keeping the tank firmly in place under the floorpan.
Submerged 400 LPH Walbro Pump Ensuring Steady Fuel Delivery
Immersing the Walbro pump in the fuel supply offers two key advantages: reduced cavitation and lower operating temperature. These factors combine to deliver consistent pressure under rapid throttle transitions, which is critical for forced induction setups and power levels above 550 horsepower. The in-tank placement also helps dampen noise and vibration, translating to quieter underbody operation. With a reliable 400 liters per hour flow rate, this pump prevents lean spikes that can damage injectors or pistons when demand suddenly spikes.
Comprehensive Kit with Matched Components for Direct Fit Installation
This all-inclusive kit arrives with the pump module, sending unit, tank straps, filler neck, vent filter, precision gaskets, and all necessary mounting hardware. Each component is laser measured to match original mounting points, cutting installation time by eliminating guesswork and custom fabrication. The calibrated sending unit provides accurate fuel level readings from initial startup through full tank, enhancing driver confidence. Technicians appreciate the clean underbody result and reduced rework when all parts align perfectly on the first try.
