Features

• CNC-machined billet aluminum construction provides a precision, direct-fit replacement for factory fuel rails with zero tolerance for misalignment or leaks
• Black anodized finish delivers superior corrosion resistance for long-term compatibility with E85, ethanol blends, and gasoline
• High-strength stainless steel mounting brackets lock rails securely to the intake manifold, preventing movement under high fuel pressure and engine vibration
• 8AN ORB (O-ring Boss) inlet and outlet ports on each rail provide a high-flow, leak-free connection rated for high-pressure return-style fuel system use
• Two 1/8" NPT auxiliary ports per rail accept fuel pressure gauges, electronic sensors, or nitrous oxide feed fittings without additional adapters
• Includes a dedicated 3/8" (10mm) EFI port fitting to supply the factory High Pressure Fuel Pump (HPFP) - a Gen 3 Coyote-specific feature critical for maintaining direct injection functionality
• Includes a 1/8" NPT pressure sensor adapter for 2018+ Mustang factory fuel pressure sensor compatibility
• Return-style design is compatible with external aftermarket fuel pressure regulators for precise, adjustable fuel pressure control in high-horsepower builds
• Designed for stock-height 60mm Coyote fuel injectors - accepts all standard Coyote port injectors
• Shorter injectors can be used with Snow Performance injector spacers (sold separately) to achieve the required 60mm seating height
• Sold as a pair - includes both driver-side and passenger-side rails for all eight port injector positions
• Designed and manufactured in the USA by Snow Performance (a Nitrous Express company)

Product Description

The Snow Performance SNF-30112 is a CNC-machined billet aluminum return-style fuel rail kit engineered specifically for the 2018+ Ford 5.0L Gen 3 Coyote V8 platform, covering the Mustang GT, and all F-150 trucks equipped with the Gen 3 engine. Sold as a complete pair, these rails bolt directly into the factory intake manifold positions on any compatible Coyote manifold - including all 1st, 2nd, and 3rd Gen GT intakes, Boss 302, GT350, Cobra Jet, and all Coyote truck manifolds - delivering a clean, show-quality appearance and the structural integrity required for high-pressure fuel system operation. The black anodized billet aluminum body and stainless steel mounting brackets provide maximum rigidity and corrosion resistance across all performance fuel types.

The SNF-30112 is specifically engineered for the Gen 3 Coyote's dual-injection architecture, which pairs port injection (PI) with Gasoline Direct Injection (GDI) via a factory High Pressure Fuel Pump (HPFP). Unlike the SNF-30012 designed for 2011-2017 engines, the SNF-30112 includes a dedicated 3/8" (10mm) EFI port fitting that maintains the low-pressure fuel supply to the factory HPFP - a critical detail that ensures the direct injection system continues to function correctly after the aftermarket rails are installed. A 1/8" NPT pressure sensor adapter is also included to retain the factory fuel pressure sensor on 2018+ Mustangs. This makes the SNF-30112 a drop-in upgrade with full compatibility for the Gen 3's dual-injection fuel system, rather than a partial solution that would disable direct injection.

Each rail features 8AN ORB inlet and outlet ports plus two 1/8" NPT auxiliary ports for fuel pressure gauges, electronic sensors, or nitrous oxide feed lines - four auxiliary ports total across the pair. This is a return-style rail, requiring an external aftermarket fuel pressure regulator and a dedicated return line to the fuel tank. Rails are designed for stock 60mm factory Coyote injectors; shorter injectors require Snow Performance injector spacers (sold separately). Not legal for sale or use in California.
