1968-1969 A-Body Cutlass/Skylark EFI Fuel Tank Kit for LS and LT Swaps
The 1968 to 1969 Oldsmobile Cutlass and Buick Skylark A Body frames demand precise contouring when installing GM LS or LT fuel systems, as suspension arms and exhaust pipes limit tank clearance. The 1968-1969 Cutlass / Skylark EFI Fuel Tank Kit - 400 LPH Pump - Notched directly solves this by featuring a notched steel reservoir that mirrors the factory well outline, avoiding floor pan trimming or ride height changes. Inside the tank the in tank module holds a 400 LPH Walbro pump to deliver stable flow for supercharged or over 550 horsepower setups. Built with heavy gauge steel, the assembly resists deformation under track and street use, and the complete package adds tank straps, sending unit, filler neck, vent filter, gaskets and mounting hardware for a drop in fit to the A Body platform.
Optimized Tank Profile
The Cutlass and Skylark EFI fuel tank kit for 1968 and 1969 features an advanced notched design that ensures clearance for exhaust routing and rear tire travel. By precisely shaping the lower contour, the assembly fits within the A Body frame rails without interfering with suspension movement or heat from header pipes. This configuration preserves valuable trunk space while eliminating the risk of contact under hard cornering or uneven road surfaces. The result is a seamless fit that maintains factory sheet metal lines and supports serious muscle car upgrades.
Fuel Delivery System Excellence
At the heart of this kit is a 400 LPH Walbro pump engineered to support supercharged power plants and engines making 550 plus horsepower. The high capacity unit delivers consistent flow under high speed and high load conditions, preventing fuel starvation during rapid throttle changes or extended track sessions. Its design resists vapor lock and provides steady pressure to downstream fuel rails all day. With heavy duty housing and reinforced connections, the assembly resists corrosion and vibration common to spirited driving and long term use.
Comprehensive Integration and Installation
This complete package is tailored for LS and LT powerplants installed in 1968 and 1969 Cutlass and Skylark models on the A Body chassis. The kit includes a precisely notched tank, integrated pickup module, sealing ring, mounting straps, gasket and all hardware necessary to complete installation without extra fabrication. Components are zinc plated to resist corrosion under tough conditions. It also aligns with MuscleRods mounts to ensure exact engine placement and correct driveshaft angles for reliable power transfer. Whether on the street or the strip, this kit streamlines EFI conversion and boosts confidence behind the wheel.
Ensure precise fuel management on your LS or LT installation and maintain smooth operation under all conditions. To explore a smaller capacity fuel pump kit at 255 LPH, consider our 1968-1969 Cutlass 255 LPH pump Tank Kit (notched).
