LS Fuel Line Fitting Kit for G-Body
If your LS swap project has you wrestling with narrow frame rails, the Fuel Fitting Kit for G-Body provides all the fittings and adapters needed to guide fuel lines with factory alignment. With precision AN fittings sized to match the G-Body sending unit, installation requires no custom adapters and maintains stable pressure under sudden load changes. Beyond leak proof connections, each component is engineered to prevent kinks and ensure consistent throttle response, making tuning sessions more predictable and keeping your engine bay tidy.
Precision AN Fittings for Reliable Fuel Sealing
The kit's AN type fittings are manufactured to tight tolerances to eliminate leaks under high pressure. These connectors thread together with exacting precision, forming a secure seal that holds up during rapid throttle changes and spirited driving. By matching industry standard sizes, the need for custom adapters is eliminated, simplifying the overall install process. This level of fit accuracy keeps system performance consistent and minimizes the risk of fuel spills for safer operation.
Direct Fit with G Body Fuel Sending Unit
Every fitting in this kit is sized specifically to mate with the factory fuel sending unit on G Body frames without modification. Presized adapters align perfectly with stock port locations, so installers avoid common assembly errors that can add hours to the swap. This direct integration streamlines routing under the chassis and keeps the engine bay layout tidy. Technicians benefit from a drop in fit that reduces installation steps and delivers predictable alignment.
Optimized Line Routing to Preserve Fuel Pressure
The geometry of each adapter is designed to guide fuel lines through narrow frame rails with minimal bends and no kinks. Maintaining a smooth path prevents flow restrictions and keeps pressure stable from pump to regulator. Consistent line diameter and length also help the fuel system hold its calibration, improving throttle response during hard acceleration. This streamlined routing makes future inspection and maintenance tasks more straightforward.
Wear Resistant Construction for Lasting Reliability
Components are crafted from premium materials chosen to withstand vibration and thermal cycling without fatigue. This durability prevents cracks and leaks that often appear in lower quality fittings after repeated stress. The corrosion resistant alloys used in each adapter guard against moisture and fuel additives, ensuring clean performance season after season. On both street and track, this robust construction delivers dependable fuel supply from startup to full throttle.
