LS and LT EFI Fuel Tank Kit for 1968-1970 Pontiac GTO and Lemans
Installing an EFI fuel tank in a 1968 to 1970 Pontiac GTO or Lemans for an LS or LT swap requires a design that clears exhaust runs and tire tubs while maintaining consistent flow. Built around a notched tank profile, this kit offers the extra clearance needed to simplify routing and secure fitment beneath the body. With its 400 LPH pump at the core, fuel delivery stays reliable under forced induction conditions or when pushing past 550 horsepower.
Notched Tank Design for Exhaust and Tire Clearance
The fuel tank features a precisely notched profile that creates extra space for exhaust pipes and tire tubs, eliminating interference under the rear body. This engineered cutaway streamlines routing and reduces the need for custom modifications during installation. By keeping the tank wall clear of header pipes, it also limits heat transfer to the fuel, minimizing vapor lock risks. The result is a secure fit beneath the A body chassis of 1968 to 1970 Pontiac GTO and Lemans at stock ride height.
400 LPH Walbro Pump Performance for High Demand
At its heart, the submerged 400 LPH Walbro pump provides a steady fuel stream capable of supporting supercharged setups and power levels beyond 550 horsepower. A robust flow rate maintains consistent fuel pressure during quick throttle transitions, whether cruising or pushing on the track. Its fully immersed design reduces cavitation, cuts operational noise, and limits heat soak for reliable delivery under high load conditions. Drivers can expect immediate throttle response and safe operation under sustained power demands.
Complete Installation Kit Simplifying LS and LT Integration
This all-in-one kit includes every component needed to swap an LS or LT engine into your classic Pontiac without hunting for missing parts. Tank straps, a vehicle-specific filler neck, vent filter and precision gaskets ensure a leak-proof seal and correct alignment. A sending unit calibrated for the GTO and Lemans provides accurate fuel level readings straight away. By packaging pump hardware with body-matched fittings, the kit removes guesswork and saves installation time, delivering a clean underbody and turnkey operation from day one.
