#10 Straight Port Plug Black

The #10 Straight Port Plug Black (MP-3002-BLK) from MAGNAFUEL/MAGNAFLOW FUEL SYSTEMS is a precision AN fitting engineered for high-pressure fuel system connections in performance and motorsport applications. This black anodized aluminum plug delivers reliable port sealing in demanding fuel injection and fuel delivery setups where secure, leak-free connections are critical to system integrity and engine performance.

Built with a #10 AN straight configuration and O-ring seal design, this fitting provides a robust compression fit that resists vibration and thermal cycling common in high-performance fuel systems. The hex head design enables straightforward installation and removal with standard wrenches, while the black anodized aluminum construction offers corrosion resistance and a finished appearance suitable for engine bay environments. The O-ring design ensures positive sealing without over-torquing, protecting against fuel weeping in critical applications.

This plug is designed for builders and technicians assembling custom fuel systems, EFI conversions, and high-performance engine builds where AN fitting standards are specified. Whether capping off unused ports in fuel rails, fuel pressure regulators, or distribution blocks, this straight port plug provides a clean, professional closure that maintains system pressure integrity. Its compact dimensions (3 x 0.8 x 3.75 inches) allow installation in confined engine bay spaces where larger fittings would not fit. MAGNAFUEL/MAGNAFLOW's AN fittings are widely recognized in the performance automotive community for consistent quality and reliable operation across thousands of racing and street performance builds.
