EFI Fuel Tank Kit for LS and LT Engines in 1968-1969 Cutlass and Skylark A-Body
Dropping an LS or LT engine into a 1968 or 1969 Cutlass or Skylark demands a steady fuel feed and this EFI tank with its 400 LPH Walbro pump delivers on demand. The built in Phantom Baffle technology traps fuel around the pickup tube during hard cornering and rapid throttle shifts to maintain constant head and prevent momentary lean spots. Precision formed from heavy gauge steel to match A Body floor contours the tank secures to original frame rails without cutting or welding and preserves factory ground clearance while supporting forced induction and high output builds. Every kit comes with a US made sending unit, precision gaskets, mounting straps and clear instructions to streamline installation.
Tailored Fitment for 1968 and 1969 Cutlass Skylark A Body
The fuel tank is formed from heavy gauge steel to follow the floor contour of the 1968 and 1969 Cutlass and Skylark underbody without any cutting or welding. It bolts directly to the original frame rails and uses the factory mounting points for straps and filler neck to preserve ground clearance and ride height. This precise fit cuts installation time and removes the need for custom modifications that can compromise structural integrity. By aligning the fuel lines and support brackets as intended by the factory, the tank remains secure under lateral loads during hard cornering.
Sustained Flow from 400 LPH Walbro Pump
At the core of this kit is a 400 liter per hour Walbro in tank pump engineered to supply engines producing over 550 horsepower or running forced induction. Its high flow capacity maintains the correct air to fuel ratio during full throttle events and prolonged high speed driving, preventing lean spots that can damage internal components. The pump's internal motor design minimizes vibration and operating heat, extending service life under continuous demand. When paired with the integrated sending unit, it delivers steady feedback to the fuel management system for accurate pressure control across all driving conditions.
Phantom Baffle Fuel Stabilization System
This tank features an internal baffling network known as Phantom Baffle technology to trap fuel around the pickup tube during acceleration, braking, and cornering. A series of chambers within the tank stops fuel from sloshing away and maintains a constant head of liquid over the pump inlet, preventing momentary starvation or air ingestion. The arrangement also dampens tank noise common in smooth walled designs, resulting in a quieter driving experience. Whether launching on a track or tackling winding roads, fuel delivery stays rock solid under all dynamic conditions.
Comprehensive US Made Kit for Simplified Installation
Every component in this kit is manufactured in the United States to tight standards for corrosion resistance and dimensional accuracy. Included are the 400 LPH Walbro pump module, sending unit, filler neck, vent filter, precision cut gaskets, mounting straps, and hardware. Detailed step by step instructions guide both professional installers and home mechanics through the process with torque specifications and wiring diagrams. Pre assembled electrical connectors and pre cut hoses reduce preparation time and assure a secure fit for a true plug and play solution.
