1968-1969 Cutlass/Skylark LS EFI Fuel Tank Kit
Whether restoring a 1968 or 1969 Buick Skylark or Oldsmobile Cutlass with an LS conversion, reliable fuel supply is critical under full throttle. The Cutlass / Skylark EFI Fuel Tank Kit with 255 LPH Pump integrates a 255 liters per hour Walbro module into the original A-Body tank envelope. Engineered for LS EFI systems, it maintains consistent pressure for engine outputs up to 550 horsepower and reduces vapor formation by keeping the pickup submerged at all driving angles. Complete with pump module, sending unit, gaskets, tank straps, filler neck, vent filter, and mounting hardware, installation preserves factory gauge accuracy and routes fuel lines clear of exhaust heat sources for steady flow during spirited runs.
Power and Flow Management
The 1968 1969 Cutlass and Skylark EFI Fuel Tank Kit features a 255 LPH Walbro high-performance fuel pump that delivers a constant volume of fuel under demanding conditions. By supporting up to 550 horsepower output it ensures that LS engine EFI conversions maintain stable pressure across a broad operating range. A constant delivery rate combined with advanced pump materials resists wear under continuous operation. Engine mapping remains consistent and tuners can rely on predictable fuel flow when dialing in performance calibrations, reducing the risk of lean spikes during acceleration.
Engineered Fitment for Classic Buick A Body Cars
Custom engineered to integrate into the original tank location of 1968 and 1969 Buick Cutlass and Skylark cars on the A Body platform, the kit uses the stock mounting points to deliver a precise fit. Installation mirrors the original factory approach with the same tank footprint so no cutting of chassis rails or frame modifications are required. This method preserves body integrity and aligns fuel lines exactly as GM intended.
Comprehensive In Tank Design and Installation
This all in one kit includes the pump sending unit level sensor and chassis side harness with a plug and play connector that matches factory style wiring. Precision gaskets and mounting hardware ensure a leak free seal while the filter sock and basket assembly provide clean fuel delivery to the pump inlet. All internal tank components are crafted from corrosion resistant material and are balanced to reduce noise and vibration. Built in diagnostic port allows quick access for pressure checks without disassembly. By consolidating these elements into a single assembly the system can be set in place and tested with minimal modification to the vehicle floor, streamlining the conversion process.
