Installation Notes

Verify the vehicle year, model, and hydroboost-to-reservoir routing before installation. Compare the original hose length, end fitting style, and routing path to Sunsong 3404886 to confirm proper alignment on the Ford F-250 Super Duty or Ford F-350 Super Duty. Inspect adjacent brackets, grommets, heat shields, bushings, and sleeves on the vehicle and replace worn components as needed to restore the system to original condition.
