Aeromotive 14103 Billet Fuel Rail Kit Red 1996-2004 Ford Mustang GT 4.6L SOHC

Vehicle Fitment

• 1996-2004 Ford Mustang GT - 4.6L SOHC (2-valve modular V8) - all trims
• Compatible with standard port injector spacing on the 4.6L SOHC (Romeo and Windsor) engine used in the SN95 and New Edge GT Mustang

Fitment Notes

• SOHC (2-valve) applications only. The 14103 is engineered for the 4.6L SOHC 2-valve GT engine. It is NOT compatible with the 4.6L DOHC 4-valve engine used in the 1996-1998 SVT Cobra or the 2003-2004 Terminator Cobra supercharged DOHC engine, which use different injector spacing and intake manifold configurations.
• Rails only - fittings and hardware are not included. The ORB-08 ports require Aeromotive PN 15628 (-8 AN) or similar ORB-08 port adapters for connection to -8 AN fuel lines. For -10 AN fuel lines, use ORB-08/AN-10 adapter PN 15641. Injectors, fuel lines, and regulator are sold separately.
• The steel mounting brackets are custom-engineered for the 1996-2004 Mustang GT intake manifold bolt pattern - bolt-on installation with no drilling, welding, or modification to the vehicle or engine required.
• This product is not legal for sale or use on emission-controlled vehicles except when used as a direct replacement part matching OEM specifications. Intended for performance, off-road, and competition applications.

Features

• 3,000 HP Flow Capacity - 5/8-Inch ID Through Bore: The 14103 rails feature a full 5/8-inch (0.625 in) internal diameter through bore - providing substantially greater internal flow area than the factory 4.6L SOHC fuel rails. The unobstructed 5/8-inch bore supports fuel delivery for up to 3,000 horsepower while eliminating the hydraulic pressure fluctuations caused by undersized or restrictive factory rail passages.
• ORB-08 Ports - Compact, Leak-Free Connections: All inlet, outlet, and crossover ports are machined as ORB-08 (O-ring boss) fittings - providing a positive, leak-free connection that outperforms barbed or flared fittings under the vibration and pressure cycling of high-performance fuel systems. Compatible with standard -8 AN port adapters or -10 AN adapters (PN 15641 sold separately) for high-flow fuel line configurations.
• Full-Size Ports at Both Rail Ends: Full-diameter ports are provided at each end of both rails - ensuring that fuel enters and exits the rail at full flow capacity for consistent injector supply pressure and minimal hydraulic fluctuation across all injectors under high fuel demand.
• Additional Inlet/Outlet Ports for Plumbing Flexibility: Additional ORB-08 inlet and outlet ports are provided at strategic locations along the rail body, allowing multiple fuel system plumbing configurations - series-flow, return-style, or dual-feed - without requiring additional external fittings or tee adapters for most common high-performance fuel system layouts.
• CNC-Machined 6061 T6 Billet Aluminum - Aerospace-Grade Construction: Each rail is precision machined from 6061 T6 aerospace-grade billet aluminum to Aeromotive's precision tolerances, ensuring exact injector bore spacing, port alignment, and dimensional accuracy for a leak-free fit with OEM-spec Bosch and compatible injector O-rings.
• Red Type II Bright Dip Anodized Finish: The bold red anodized finish provides corrosion resistance against fuel, moisture, and engine bay heat while delivering a clean, finished appearance that complements both stock and high-performance engine bay builds.
• Custom-Engineered Steel Mounting Brackets - Bolt-On Installation: The steel mounting brackets are custom engineered for the 1996-2004 Mustang GT intake manifold, providing correct fuel rail positioning and a solid, vibration-resistant mounting platform. Installation replaces the factory fuel rails directly - no cutting, drilling, or permanent modification to the vehicle required.

Product Description

The Aeromotive 14103 is a CNC-machined billet aluminum fuel rail kit for the 1996-2004 Ford Mustang GT equipped with the 4.6L SOHC 2-valve modular V8 - a direct bolt-on replacement for the factory fuel rails combining up to 3,000 HP flow capability with precise OEM-fit installation. Sold as a pair, the rails feature a full 5/8-inch ID through bore and ORB-08 ports at all inlet, outlet, and crossover locations for compact, leak-free -8 AN fuel line connections.

The 5/8-inch bore eliminates the flow restriction and hydraulic fluctuation inherent in the factory 4.6L SOHC fuel rails, providing consistent injector supply pressure across all eight cylinders at the high fuel flow rates demanded by modified, supercharged, and turbocharged 4.6L SOHC Mustang builds. Custom-engineered steel mounting brackets are included for direct bolt-on installation on the stock GT intake manifold. Red Type II bright dip anodized finish. Rails only - AN fittings sold separately (PN 15641 for AN-10 adapters). Not for DOHC/Cobra applications. 1-year warranty.
