Keep hydraulic pressure moving from the hydroboost unit to the steering gear with the Sunsong Power Steering Pressure Line Hose Assembly 3401390. This hydroboost-to-gear pressure line is a direct-fit replacement for the 1997-1998 Ford Mustang, carrying pressurized power steering fluid so the system can deliver steering assist.
- Pre-assembled with brackets: ships ready to install, cutting labor time versus hoses sold as individual pieces.
- Precision-engineered fit: built to an exact fit and supplied with the additional components needed to restore the wearable parts to original condition.
- High-pressure construction: the pressure hose is rated for a max working pressure of 1,500 psi, a burst pressure of 8,700 psi, and a tensile strength of 1,600 lb for durability.
- Factory tested: every pressure hose is subjected to a high-pressure quality assurance test before it leaves the factory.
Signs this line may need replacing include power steering fluid leaks along the hose, a low reservoir, or a whine and hard steering from air or lost pressure. Confirm the leak is at the pressure line before replacing.
