1968-1969 Cutlass Skylark A-Body EFI Fuel Tank Kit for LS LT

For a seamless LS and LT powerplant installation in your Cutlass or Skylark A Body chassis, this notched fuel tank kit eliminates exhaust and tire interference with precision engineered clearances. The integrated 400 LPH Walbro pump maintains consistent fuel flow for up to 550 horsepower under street and track conditions, while the comprehensive kit includes mounts, hoses, and hardware for a hassle free EFI setup.

EFI Fuel Tank Kit for 1968-1969 Oldsmobile Cutlass and Buick Skylark LS and LT Swaps

When tackling an LS or LT swap in a Cutlass or Skylark from 1968 to 1969, your choice of fuel tank plays a critical role in avoiding interference with suspension mounts and exhaust plumbing. This notched steel tank kit includes a 400 LPH Walbro pump pre-installed inside the reservoir to maintain consistent pressure on hard acceleration without external brackets or fittings. Installers benefit from contours that mirror the original fuel well and a complete set of straps, gaskets, sending unit and filler hardware that eliminates the hunt for adapters and potential leak points. Built from thick gauge steel with reinforced welds and a protective finish that resists corrosion, it ensures reliable fuel delivery through street driving or track sessions under the load of LS or LT engines above 500 hp.

In Tank Cooling and Pressure Consistency

Placing the 400 LPH Walbro pump inside the tank leverages the surrounding fuel as a heat sink, reducing the operating temperature of the pump motor. This cooler environment slows wear on internal components and extends the interval between service visits. By integrating the pump module within the reservoir, plumbing runs are shorter and potential leak points are minimized, which simplifies system routing in the Cutlass or Skylark A-Body chassis. The result is a sustained fuel pressure even during rapid throttle transitions and sustained high load driving with LS or LT engines.

Chassis Contour Matching for Precise Fitment

The notched tank design mirrors the factory fuel well geometry of 1968-1969 Oldsmobile Cutlass and Buick Skylark models, preserving critical clearance for suspension mounts and exhaust plumbing. Installers can align the tank without altering the chassis, maintaining original ground clearance and ride height. This faithful reproduction avoids interference under heavy cornering or when the rear axle articulates over bumps. By following OEM contours, the tank sits snugly in place, eliminating stress points that can lead to noise or premature material fatigue.

Comprehensive Hardware Integration for Streamlined Installation

This kit delivers every component required for a complete EFI upgrade, including the in-tank fuel pump module, sending unit, tank straps, filler neck, vent filter, gaskets, and mounting hardware. Each element is sized to match existing openings, removing the need to hunt for aftermarket adapters or fittings. The coordinated approach ensures leak-free connections and cuts installation time by consolidating multiple parts into a single package. Technicians benefit from a predictable workflow whether fitting a street cruiser or a track oriented build.

Reinforced Steel Construction for Enduring Reliability

Fabricated from thick gauge steel, the tank resists the impacts and vibrations common in performance driving without deforming. Reinforced welds at critical seams maintain structural integrity through repeated fill cycles and pressure changes, while the protective finish sheds moisture and guards against corrosion from modern fuel blends. This robust construction supports LS or LT swaps up to 550 horsepower, giving builders confidence in long-term durability on street or track. The result is consistent fuel storage capacity and secure mounting in a demanding engine swap application.

Enjoy consistent performance and reliable delivery from this fuel tank kit. To complete your smaller capacity fuel pump kit consider our 1968-1969 Cutlass 255 LPH pump Tank Kit (notched) which shares the same precise fit and durable finish.
