The Nitrous Express 5/16" to 6AN fuel rail adapter provides a simple, threaded transition to connect a 5/16" factory fuel feed to a 6AN line for aftermarket plumbing or nitrous installations. It lets you mate braided AN fuel hose or fittings to a smaller rail without modifying the rail itself, making upgrades or repairs straightforward and keeping fuel routing neat and reliable in custom fuel systems.
