Mustang Fuel Rails: When Power Goes Up, Stock Rails Tap Out

Building an S650 fuel system shouldn’t involve praying the stock rails keep up. The SPE Motorsport S650 Mustang Coyote Fuel Rail Kit is a straight-up foundation upgrade: 6061 billet rails, -8AN ORB fittings, black hard-anodized finish, and billet brackets (aka not sheet-metal sadness). We kept the factory fuel pressure sensor but changed the port angle for better harness clearance—because fighting a connector at midnight is not a vibe. Bonus: dual 1/8” NPT ports on each rail for gauges, sending units, or auxiliary feed.
