Installation Notes and Tips

Verify end fitting sizes and types before installation: 14 mm male O-ring on one end and 11 mm captive O-ring on the other. Confirm routing and clearance against the original hose path on the vehicle, and inspect adjacent steering components for wear or contamination before refilling and bleeding the system.
