#3 Bulkhead Tee-On the Run Black

The #3 Bulkhead Tee-On the Run Black from Fragola is a compact hydraulic and fuel line tee fitting designed for performance enthusiasts building custom cooling systems, brake line circuits, and fuel distribution networks. If you're fabricating a custom cooling loop, integrating auxiliary fuel pressure sensors, or routing secondary brake circuits in a modified engine bay, this tee connector provides a reliable junction point where precision matters. Fragola's reputation for quality in motorsports plumbing makes this fitting an industry standard among engine builders and fabricators tackling serious modifications.

This bulkhead tee features a #3 SAE port size, which accommodates -3 AN hose and tubing—a common specification in modern EFI conversions and turbo setups where space efficiency and flow management are critical. The compact black anodized aluminum construction resists corrosion in harsh engine bay environments while maintaining lightweight characteristics essential for weight-conscious builds. The threaded bulkhead design allows panel or firewall mounting, enabling clean line routing and organized plumbing layouts without sacrificing performance or aesthetic coherence in visible engine compartments.

Street rodders, turbocharged engine builders, and vintage car restorers with modern fuel injection systems benefit most from this versatile fitting. Whether you're splitting coolant flow to secondary radiators, creating gauge sensor takeoffs, or establishing redundant fuel distribution for high-horsepower applications, the #3 Bulkhead Tee-On the Run integrates seamlessly into -3 AN hose systems. Installation is straightforward—firewall or panel mounting via the bulkhead thread, with three ports available for inbound and outbound lines. Verify your port size matches -3 AN requirements before ordering to ensure compatibility with existing or planned line configurations.
