1968-1969 A-Body LS EFI Fuel Tank Kit for Cutlass/Skylark
For a smooth LS engine swap in a 1968 to 1969 Oldsmobile Cutlass or Buick Skylark, ensuring steady fuel feed under varying loads is a top priority. This EFI Fuel Tank Kit features a 255 LPH pump housed in a notched tank engineered to clear exhaust and tire obstructions while slotting precisely in the A-body frame. Beyond stable delivery, this kit supports builds up to 550 hp and simplifies installation on classic Cutlass and Skylark bodies.
Optimized Fuel Pump Capacity for LS Applications
This kit centers on a 255 LPH Walbro fuel pump engineered to maintain a stable flow under extreme engine loads. By delivering consistent volume, it prevents lean spikes during wide-open-throttle runs and supports engine builds rated up to 550 hp. Riders will notice sharper throttle response and more predictable power delivery thanks to the pump's ability to keep pressure constant across varying RPM ranges. This level of fuel management is crucial for both spirited street driving and track duty, ensuring the LS powerplant never starves for fuel.
Precision Tank Contouring for A-Body Frame Integration
The tank's notched design is the result of careful CAD modeling to provide maximum capacity while clearing exhaust pipes and rear suspension components. Each contour aligns with the Cutlass and Skylark's original frame rails, allowing the module to slide into place without trimming or hammering. This geometry also preserves ground clearance and keeps the tank out of harm's way from road debris. The result is a near-factory fitment that upholds the classic car's underbody integrity.
Full Spectrum Kit Components to Expedite Installation
Rather than sourcing parts piecemeal, this complete kit bundles the in-tank pump module, sending unit for accurate level readings, sturdy tank straps, replacement filler neck, vent filter and all necessary gaskets and mounting hardware. Each component is selected to match the original A-body mounting points and ensure a leak-free seal. With everything included, installers can focus on bolting in the assembly and making fuel line connections, cutting hours off the swap process.
Engineered Fitment for Classic Cutlass and Skylark Bodies
From the pickup screen to the mounting flanges, every element of this fuel tank assembly is tailored to the 1968-1969 Oldsmobile Cutlass and Buick Skylark. Precision spacing between the filler neck and quarter panel ensures the gas cap lines up exactly as it did from the factory. This attention to dimension and alignment removes guesswork, eliminates custom brackets and helps maintain the vehicle's original appearance beneath the bodywork.
