Keep power steering fluid flowing under pressure with the Sunsong Power Steering Pressure Line Hose Assembly 3403019. This pressure line carries pressurized fluid from the power steering pump to the steering gear, and it installs as a direct-fit replacement for the 1984-1985 Mercedes-Benz 380SE, 1982-1983 380SEC, 1981-1983 380SEL, 1986-1991 420SEL, 1984-1985 500SEC, 1984-1985 500SEL, 1986-1991 560SEC, and 1986-1991 560SEL. See the Buyer's Guide tab for engine-specific details.
- Pre-assembled with brackets: arrives ready to fit for easier installation and reduced labor time versus versions sold as individual hoses.
- High 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.
- Complete assembly: precision engineered to exact fit and includes the additional components needed to restore wearable parts to original condition.
- Factory tested: every pressure hose is subjected to a high-pressure quality assurance test before leaving the factory.
Signs the original line may need replacing include power steering fluid leaks, cracked or chafed hose, or a whine and stiff steering from air or low fluid. If a failed pressure hose is the cause, this assembly replaces it.
