1968-1969 A-Body Cutlass/Skylark EFI Fuel Tank Kit for LS Swaps with 255 LPH Pump
Swapping an LS engine into a vintage A-Body Oldsmobile or Buick often exposes the stock tank's limitations under heavy throttle, so this kit brings a 255 LPH pump together with a notched fuel container sculpted to clear exhaust and rear suspension rails. By maintaining proper pressure for builds up to 550 horsepower the assembly keeps injectors fed without risk of lean peaks during hard launches or prolonged wide open throttle stretches. Mounting flanges, filler neck, and vent filter line up with original bracket points for a direct fit that preserves chassis ground clearance and removes the need for sheet metal trimming. Installers can focus on routing lines and securing hardware instead of chasing extra parts thanks to this complete solution.
Sustainable Fuel Delivery for LS Swaps
The 255 LPH pump at the core of this kit is calibrated to sustain pressure for engine builds approaching 550 hp, ensuring injectors receive a continuous supply of fuel under full throttle. By matching pump output to the high flow requirements of an LS conversion, the system eliminates lean spots that can interrupt power delivery or cause detonation. The in-tank module design keeps the pickup submerged even during rapid acceleration or cornering, reducing the risk of vapor lock and slosh-induced fuel starvation. This stable delivery profile translates to predictable throttle response and consistent performance whether you're carving canyons or laying down laps on the track.
Tank Geometry Tailored to 1968 – 1969 A Body Clearance
Developed from precise CAD scans of 1968 and 1969 Cutlass and Skylark underbodies, the tank's sculpted notch clears exhaust pipes and rear suspension links without trimming factory sheet metal. This custom contour preserves chassis ground clearance and maximizes usable capacity by fitting snugly against frame rails. The seamless integration shields the container from road debris and potential impacts by following the original underbody envelope. Installers benefit from a bolt-in solution that honors the stock profile and avoids time-consuming modifications.
All-Inclusive Fuel Assembly for Streamlined Installation
This comprehensive kit arrives complete with the fuel pump module, sending unit, tank straps, filler neck, vent filter, gaskets and all required hardware to finish the job. Each component is engineered to interface precisely with the existing openings on the Cutlass and Skylark bodies, delivering leak-free seals and proper alignment right out of the box. By consolidating every critical piece into a single package, the assembly process is simplified and build times shrink. Installers can focus on routing lines and verifying connections instead of tracking down compatible parts.
