The factory uses plastic retainers for securing the OEM feed and EVAP lines. These fuel lines run from the back to the front of the vehicle. This Radium Engineering kit uses billet aluminum retainers that replace the OEM variations. Additionally, they permit extra hose locations for large aftermaket fuel lines, as depicted below.
 
 
No drilling, cutting, or any permanent modifications are required. Mounting hardware is provided using OEM threads.
