EFI Fuel Tank Kit for LS Swap in 1968-1969 Cutlass/Skylark A-Body
Fuel starvation under hard acceleration can cripple an LS conversion and the 1968 to 1969 Cutlass and Skylark EFI Fuel Tank Kit prevents this by pairing a 255 LPH pump with a notched tank shaped to A Body frame rails. Contours molded to clear exhaust and rear suspension preserve chassis ground clearance and maximize usable fuel capacity without trimming sheetmetal. The 255 LPH pump sustains pressure for builds up to 550 hp so injectors stay fed under wide open throttle. Mounting flanges and the filler neck align with stock locations on A Body Oldsmobile and Buick bodies and include brackets hardware and a vent filter for a ready to mount assembly.
Steady Fuel Supply for 550 hp LS Applications
The 255 LPH pump delivers a consistent and robust flow during wide open throttle runs and abrupt throttle transitions. By matching the fuel demands of builds up to 550 horsepower this assembly prevents lean peaks that can compromise power output or risk engine damage. The design maintains stable injector pressure under sustained high demand and minimizes fuel slosh during acceleration or cornering. Drivers will notice uniform engine response whether cruising on the street or pushing the pace at the track.
Notched Tank Geometry Optimized for A Body Clearance
Engineered from precise CAD data of 1968 and 1969 Cutlass and Skylark underbodies the tank features a sculpted notch that clears exhaust tubing and rear suspension links. This contour increases usable volume while preserving factory ground clearance and eliminating the need for sheet metal trimming. By hugging the frame rails the shape protects the tank from road debris and potential impacts. The result is a seamless integration that respects the original chassis layout and frees up installation time.
Complete Pump Module Bundle for Simplified Installation
This kit arrives with the in tank pump module sending unit tank straps filler neck vent filter gaskets and all necessary mounting hardware to complete the assembly without sourcing extra parts. Each piece is engineered to interface directly with existing fuel and filler openings on Cutlass and Skylark bodies ensuring leak free seals and precise alignment. Consolidating these components into a single package reduces build complexity and accelerates fitment. Installers can focus on securing the unit and routing lines rather than hunting for compatible parts.
Stock Fitment Maintains Classic Underbody Profile
Mounting flanges and filler neck are positioned to match original bracket points and quarter panel cutouts so the gas cap aligns exactly as delivered from the factory. This attention to dimension preserves the clean underbody appearance of your Cutlass or Skylark and avoids the need for custom adapters or brackets. By upholding factory style alignment the kit safeguards both the vehicle's aesthetic and structural integrity. Owners gain modern EFI performance while retaining the classic heritage of their A Body ride.
