The Nitrous Express 4AN male x 1/16 NPT male Ford fuel rail fitting replaces the Schrader valve on Ford engines, allowing attachment of a 4AN line to the factory fuel rail. It provides a direct way to tap Ford fuel rails for aftermarket AN plumbing without modifying the rail, enabling connection of aftermarket fuel lines or fittings where a 4AN feed is required.
