1968-1969 Cutlass/Skylark A-Body LS Swap EFI Fuel Tank Kit with 255 LPH Pump
When swapping an LS engine into a 1968 to 1969 Cutlass or Skylark the factory tank often falls short under sustained high demand. This notched steel container and integrated 255 LPH pump deliver consistent pressure for up to 550 hp applications while clearing exhaust tubing and rear suspension rails without trimming sheet metal. Matching pump output to EFI requirements and aligning mounting flanges with existing bracket points simplifies installation in the A-Body platform and keeps focus on line routing instead of part sourcing. Installers benefit from a complete kit that includes the pump module, sending unit, filler neck, vent filter, gaskets, straps and hardware to ensure leak free seals from day one.
Efficient Fuel Delivery Optimized for LS Engine Demands
The 255 LPH high-flow fuel pump at the heart of this kit is calibrated specifically for the volume requirements of LS engines up to 550 hp. By supplying a consistent stream of fuel, it prevents lean conditions that can lead to hesitation, detonation, or power loss under aggressive acceleration. The internal module design keeps the pickup submerged even during rapid starts or tight cornering, reducing the risk of vapor lock and fuel starvation. This stability under dynamic conditions delivers reliable throttle response whether you are cruising or pushing the limits at the track. Matching pump output precisely to the injector flow ensures that pressure remains within the optimal range for electronic fuel injection systems during sustained wide open throttle events.
Sculpted Tank Profile for Exhaust and Suspension Clearance
Engineers used detailed CAD scans of 1968 and 1969 A-body underbodies to sculpt the fuel tank's notched contour, ensuring unobstructed clearance to factory exhaust pipes and rear suspension rails without trimming metal. This tailored shape preserves ground clearance while maximizing usable fuel capacity by hugging the frame rails. Heavy-gauge steel construction and reinforced welds around the notch deliver structural integrity and prevent stress points under load. The form-fitting design also shields the container from road debris and side impacts, extending service life. Installers benefit from a bolt-in solution that aligns with existing mounting flanges and preserves the original underbody envelope.
Complete Assembly for Streamlined EFI Integration
This all-inclusive kit arrives with every component required to upgrade the fuel tank for an LS swap in a 1968-1969 Cutlass or Skylark. It includes the fuel pump module for consistent delivery, a sending unit for accurate level indication, a filler neck engineered to match the factory opening, and a vent filter that keeps contaminants out. You also receive precisely shaped gaskets and treated tank straps to secure the container to the frame, plus all required hardware for leak-free seals. By consolidating these parts into one package, the installation process is simplified and the need to source separate items is eliminated. Technicians can focus on routing lines, verifying connections, and completing the build without delays.
