This PSC replacement return hose connects the hydro-boost unit to the power steering pump on 2007.5-2010 GMC 2500HD and 3500HD 4WD trucks equipped with the 6.6L Duramax engine. The hydro-boost system relies on clean, unrestricted fluid return flow for proper brake assist and steering performance.

Replacing an old or leaking hose helps keep the hydraulic system operating the way it should while preventing fluid loss and contamination. This hose is built as a direct-fit replacement for servicing factory-style steering and hydro-boost systems.
