How to Install AN Fuel Lines | Mustang Fuel System Upgrade In this video, I walk you through the complete process of installing AN fuel lines on my Mustang project. From prepping hard fuel lines to routing braided hoses, adding an inline fuel pressure gauge, and connecting everything to the fuel rails, this step-by-step guide has you covered! 🔧 *What’s Covered in This Video:*

• A quick history of AN fittings (Army/Navy origins)

• Removing old fuel lines and prepping hard lines

• Installing AN fittings with olives (1/4" and 5/16")

• Routing braided fuel lines safely around exhaust and sharp edges

• Adding an inline fuel pressure gauge for easy monitoring

• Connecting to Foxbody Mustang-specific fuel rails

This project is another step toward getting this Mustang back on the road, and I couldn’t be more excited to share it with you!
