Metco MFR2011A , 2011+ Mustang Fuel Rail Kit 5.0 4V
Billet Fuel Rail Kit
2011 & Newer Mustang
Like all Metco Motorsports fuel rails, these rails are precision-machined from billet, not extruded stock like most other aftermarket fuel rails. These rails have the largest-available internal diameter at 11/16". This large internal volume ensures that the maximum amount of fuel is available at the injector and pump pulsations and pressure variations are minimized.
As shipped, the complete kit includes USA-made black-anodized swivel fittings at the rear for the included braided steel crossover, and a matching port plug for the front of the passenger-side rail. An optional feed-line adapter (shown), Metco Motorsports part number MFRS2000, can be added to make the connection to the OEM fuel feed line a simple process.
The rail set includes one driver's side rail with (2) 1/8" NPT ports to facillitate the installation of a fuel pressure gauge, nitrous system, or both, and one passenger side rail machined with a smooth top. Stainless pipe plugs are included for any unused ports in the driver's side rail.
Our fuel rails have 3/4-16 (also referred to as 8AN straight-thread) female threads in the ends, and use standard ORB-style fittings.
