LS and LT Fuel Tank Kit for 1968-1970 Pontiac GTO/Lemans
For a smooth LS or LT engine swap in a classic A-Body Pontiac, the 1968-1970 GTO / Lemans EFI Fuel Tank Kit uses a 400 LPH pump to deliver consistent fuel flow while clearing exhaust runs and tire tubs. Its notched tank profile creates extra room for header pipes and rear suspension components, ensuring routing without interference beneath the body. Constructed from heavy gauge steel and featuring a submerged Walbro unit, the system limits heat soak and cavitation to support boosted setups or power levels above 550 horsepower.
Optimized Notched Profile for Exhaust and Tire Clearance
The fuel tank's notched geometry creates precise pockets to clear header pipes and rear tire tubs under the A body chassis. This shaping allows direct routing of exhaust components without risk of contact or heat exposure. By maintaining a uniform wall thickness around the cutout, the design limits fuel heat soak and prevents vapor lock in high stress situations. Installers benefit from a reduced need for custom metal work and can achieve a secure fit at stock ride height.
Submerged 400 LPH Walbro Pump for Consistent Flow
The in tank Walbro pump delivers a robust 400 liters per hour flow rate to support engines pushing beyond 550 horsepower. Immersing the pump in fuel reduces cavitation and heat buildup, so pressure remains stable during rapid throttle changes. This consistent delivery is critical for supercharged setups where fuel starvation can lead to lean conditions and potential engine damage. Drivers will notice improved throttle response and confidence under sustained load.
Heavy Gauge Steel Body for Enhanced Durability
Constructed from high gauge steel, the tank resists deformation and protects internal components against road hazards. The sturdy build also dampens vibration and maintains seal integrity over time. Unlike thin wall units prone to seam failure, this design ensures a leak free operation even in high stress applications. Routine maintenance is simplified thanks to durable surfaces that withstand cleaning solvents and garage spills.
Complete Installation Kit Tailored for LS and LT Swaps
This all in one kit includes the pump module, tank straps, filler neck, vent filter and precision gaskets needed for a direct fit under 1968 to 1970 GTO and Lemans. A calibrated sending unit provides accurate fuel level readings from the moment you power up. By matching hardware to the original mounting points, the kit eliminates hours of trial and error and supports a clean underbody finish. Technicians can expect seamless integration and reliable performance straight out of the box.
