1968-1969 Cutlass/Skylark EFI Fuel Tank with 400 LPH Pump for LS and LT Swaps
When transplanting an LS or LT engine into a 1968-1969 Cutlass or Skylark an EFI fuel tank kit with a 400 LPH pump maintains consistent fuel supply during aggressive acceleration and tight cornering. With Phantom Baffle technology built into the interior the system corrals fuel around the pickup tube to prevent momentary starvation and lean conditions. The precision formed steel tank bolts directly to original A Body frame mounts so installation requires no cutting or welding while factory ground clearance is preserved. Detailed instructions accompany the US made Walbro module and sending unit while the sturdy construction supports forced induction and engine outputs beyond 550 horsepower.
Seamless Drop In Fitment for Cutlass and Skylark A Body
The fuel tank is precision formed from heavy gauge steel to match the contours of the 1968 and 1969 Cutlass and Skylark underbody without any cutting or welding. It secures directly to the original frame rails and uses factory mounting points for straps and filler neck, preserving the factory ground clearance and ride height. This tailored fitment reduces installation time and eliminates the guesswork that comes with generic replacements. By aligning fuel line connections and support brackets exactly as the factory intended, the tank remains stable under high lateral loads and aggressive maneuvers. The drop in nature of the assembly minimizes stress on hoses and ensures reliable operation on both street and track applications.
Robust Fuel Delivery from a 400 LPH Walbro Pump
At the heart of this kit is a 400 liter per hour Walbro in tank pump designed to sustain engines producing in excess of 550 horsepower or running forced induction. Its flow capacity maintains proper air fuel ratio during wide open throttle events and extended high load driving, preventing lean spots that could damage internal components. The pump's internal motor design reduces vibration and heat generation, contributing to a longer service life even under continuous demand. Paired with the integrated sending unit, it offers precise feedback to the fuel management system, ensuring stable pressure and volume control across varying driving conditions. Enthusiasts will appreciate the quiet operation and consistent performance from idle through redline.
Phantom Baffle Fluid Management Technology
This tank features an advanced baffling system built into the interior walls to trap fuel around the pickup tube during acceleration, braking, and tight cornering. A network of chambers prevents fuel from sloshing away, maintaining a constant head of liquid and avoiding momentary fuel starvation or air ingestion. The design also cuts tank noise that is common in smooth walled containers, delivering a smoother driving experience. By keeping voltage draw steady and preventing pump cavitation, the baffle arrangement safeguards both the motor and the engine's fuel demands. Whether you're pushing hard on a winding back road or laying rubber off the line, fuel delivery stays rock solid.
Complete Kit with US Made Components for Streamlined Installation
Every component in this kit is manufactured in the United States to precise 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 all required hardware. Clear, step by step instructions with torque specifications guide both professional shops and seasoned hobbyists through the entire installation process. Preassembled electrical connections and pre trimmed hoses reduce preparation time, while quality hardware ensures a secure fit. The end result is a true plug and play solution that removes guesswork and lets you focus on final tuning rather than fabrication.
