1968-1969 A-Body Cutlass/Skylark LS and LT EFI Fuel Tank Kit
When converting a 1968-1969 Cutlass or Skylark A-Body to LS or LT EFI power, a fuel tank that clears exhaust pipes and suspension mounts becomes critical. This kit pairs a notched steel tank profile that matches factory contours with a high flow 400 LPH Walbro pump to maintain consistent pressure during hard acceleration. Including straps, gaskets, a sending unit and all mounting hardware removes the need for aftermarket fittings or chassis modifications. The durable steel construction resists corrosion and stress from street or track use so your EFI swap maintains reliable fuel delivery under load.
In-Tank Pump Placement for Cooler Operation
Mounting the 400 LPH Walbro pump inside the tank keeps it submerged in fuel, which dissipates heat more effectively than an external location. This lower operating temperature reduces wear on internal components and extends service intervals. The integrated module design also minimizes plumbing runs, cutting down on potential leak points and simplifying pressure maintenance. Combined with a precise flow rate, this configuration ensures steady delivery even during rapid throttle transitions.
Precision Notch Matches Factory Fuel Well Geometry
The tank's notched contour mirrors the original fuel well layout of 1968-1969 Cutlass and Skylark models, so installers can align it without modifying the chassis. By preserving factory clearance around suspension mounts and exhaust pipes, the design ensures that tire travel and exhaust flow remain unobstructed. This faithful replication of OEM form prevents rubbing and stress points under heavy cornering. The result is a ready fit that maintains the car's ground clearance and ride quality.
Complete Component Suite for Effortless EFI Setup
Every part needed for a fuel system upgrade is included, from the sending unit and tank straps to the filler neck, vent filter and hardware. Each gasket and fitting is sized to match factory openings, which removes the need to source aftermarket adapters. This coordinated approach lowers the risk of leaks and ensures a clean installation process. Technicians benefit from fewer steps and consistent results, whether they are working on a street cruiser or a competition build.
Durable Steel Construction Resists Corrosion and Damage
Made from thick gauge steel, the tank withstands impacts and the vibration common in performance driving without deforming. Its protective finish sheds moisture and resists degradation from ethanol blends and fuel additives. Reinforced seam welds hold up under repeated fill cycles and pressure fluctuations, so the container maintains its shape and capacity over time. This robust build gives drivers the confidence to push their powertrain without worrying about fuel storage integrity.
