Keep power-assisted steering fluid moving under pressure with the Sunsong Power Steering Pressure Line Hose Assembly 3401025. It installs as a direct-fit replacement for the 1997-2001 BMW 740I and the 1996-2001 BMW 740IL — see the Buyer's Guide tab for engine-level applications. This assembly carries pressurized fluid from the power steering pump to the steering gear, and it may need replacing when you see fluid seepage at the fittings, a whine or hard steering from low pressure, or cracked/leaking hose.
- Pre-assembled with brackets: the pressure and return hoses come assembled with brackets for easier installation and reduced labor time versus replacements sold as individual hoses.
- Precision engineered to exact fit: includes the additional components needed to restore the wearable parts to original condition.
- Exceeds OE pressure ratings: 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 and long life.
- Factory-tested: every pressure hose is high-pressure quality-assurance tested before it leaves the factory for trouble-free installation and operation.
