#10 Straight Port Plug Black

The #10 Straight Port Plug Black (MP-3002-BLK) from Magnafuel is a precision fuel system component designed for builders and mechanics who demand reliable, leak-free connections in high-performance fuel delivery systems. This straight port plug serves as a critical blocking fitting for fuel manifolds, rails, and distribution blocks where port access isn't needed.

A quality port plug prevents fuel leaks and maintains system integrity under boost and heat. Magnafuel's engineering ensures this straight port plug delivers consistent performance across fuel systems running gasoline, naturally aspirated, turbocharged, or supercharged engines. The black finish resists corrosion and blends seamlessly into engine bay aesthetics while the straight-port design provides direct, unobstructed flow paths when used as an active fitting and complete blockage when sealing unused ports.

Compact dimensions (3 × 0.8 × 3.75 inches) and minimal weight (0.05 lbs) make installation straightforward on tight manifolds and fuel rails without adding bulk or complexity to plumbing runs. Experienced fuel system builders, drag racing teams, and street performance enthusiasts rely on Magnafuel port plugs to eliminate guesswork and potential weeping at unused connections. This plug integrates seamlessly into manifold blocks with #10 straight ports, common in Holley and other performance applications.
