Regulator Plumbing Kit

The Regulator Plumbing Kit from Magnafuel/Magnaflow Fuel Systems is a precision fitting assembly designed for custom fuel system builds and high-performance fuel pressure regulation installations. This kit serves technicians, hot rod builders, and automotive enthusiasts who require reliable, leak-free connections between fuel regulators and fuel lines. The kit's mixed AN fitting configuration provides flexibility for systems where different port sizes must communicate efficiently while maintaining pressure integrity.

Constructed from aluminum with a durable purple anodized finish, the Regulator Plumbing Kit includes one straight-fitting 10 AN male-to-male O-ring adapter and four 6 AN male-to-male O-ring adapters, engineered for the Magnafuel 4-port regulator platform. The O-ring face seal (ORFS) design ensures superior sealing performance compared to traditional NPT or JIC connections, reducing the risk of fuel leaks under pressure cycling. The aluminum construction offers corrosion resistance and lightweight characteristics essential for fuel system applications, while the anodized finish protects against oxidation and provides visual identification on the bench or in the engine bay.

Engine builders and fuel system integrators benefit most from this kit when configuring multi-port fuel regulators for boost-referenced or manifold-absolute-pressure (MAP) applications. Installation is straightforward: the straight-fitting configuration prevents 90-degree turns that can restrict flow, and the combination of 10 AN and 6 AN sizes accommodates various plumbing scenarios—main feed lines typically use 10 AN while auxiliary signal or return lines use the smaller 6 AN fittings. Compatibility is confirmed for all four-port Magnafuel regulators; verify your regulator's port configuration before ordering to ensure proper fit and function.
