The Radium 20-1814 Fuel and Brake Line Retainers replace the plastic clips that secure the OEM hard lines underneath the 2015+ Ford Mustang. The billet aluminium clamps support a large aftermarket fuel feed line alongside the OEM lines.
The OEM feed hard line is repurposed as the return line in Radium's Mustang fuel hanger plumbing kits, and these retainers are designed to secure an 8AN PTFE feed hose. Check the dimensions in the retainer drawing to confirm fit with rubber, braided, PTFE, aluminium or steel lines.
