EFI Fuel Tank Kit for 1968-1969 Cutlass/Skylark A-Body LS and LT Swaps
Swapping an LS or LT mill into a 1968 or 1969 Cutlass or Skylark A-Body demands a fuel tank that keeps pace with modern EFI systems so this kit pairs a 400 LPH Walbro pump with integrated baffling to prevent starvation under lateral loads. Formed from heavy gauge steel to match the original floor contour and bolted to stock frame rails it needs no cutting or welding and preserves ground clearance. A network of partitions known as Phantom Baffle technology traps fuel around the pickup tube during cornering and braking to maintain constant head at the pump inlet. Complete with US made sending unit precision gaskets mounting straps and clear instructions this kit simplifies installation for swaps producing over 550 horsepower or running forced induction.
Precision Fit for 1968 and 1969 Cutlass and Skylark A Body
The fuel tank is precision formed from heavy gauge steel to follow the unique floor contours of 1968 and 1969 Cutlass and Skylark models. By utilizing the factory frame rail mounting points and original filler neck location, it eliminates the need for any cutting or welding, preserving factory ground clearance and ride height. This exacting fitment also aligns fuel lines and support brackets as intended, preventing interference with suspension components or brake lines. As a result, installation time is reduced and potential structural compromises from custom modifications are avoided.
Reliable Delivery from the 400 LPH Walbro Pump
At the heart of this kit lies a 400 liter per hour Walbro fuel pump engineered to support engines producing over 550 horsepower or equipped with forced induction. Its high capacity capability maintains the correct air to fuel ratio during full throttle acceleration and sustained high speed operation, preventing lean spots that can lead to detonation or engine damage. The pump's robust internal motor design minimizes vibration and operating temperature, extending service life under continuous demand. When integrated with the included sending unit, it provides steady feedback to the ECU for precise pressure regulation across all driving conditions.
Phantom Baffle Technology for Consistent Fuel Head
This tank employs an internal baffling network known as Phantom Baffle technology to trap fuel around the pickup tube during cornering, braking, and rapid throttle changes. A series of interconnected chambers within the tank prevents fuel from sloshing away from the pump inlet, maintaining a constant fuel head and ensuring uninterrupted flow. By reducing the chance of air ingestion, it safeguards against momentary lean conditions that can occur under high lateral loads. The baffling also dampens tank noise often associated with smooth-walled designs, contributing to a quieter and more refined driving experience.
Complete US Made Kit for Streamlined Installation
Every component in this assembly is manufactured in the United States to strict standards for corrosion resistance and dimensional accuracy. The kit includes the high-capacity pump module, a precision sending unit, filler neck, vent filter, gaskets, mounting straps, and all necessary hardware. Detailed instructions guide both professional installers and home mechanics through each step, providing torque specifications and wiring diagrams where needed. Preassembled electrical connectors and pre-cut hoses further reduce preparation time, allowing for a straightforward installation that delivers reliable performance from day one.
