Power Steering Pressure Line for Mercury Applications
The Sunsong 3401737 power steering pressure line hose assembly is built for Mercury steering systems that require a precise OE-style hydraulic connection. It is engineered for the pressure side of the system with a 1,500 psi max working pressure, 8,700 psi burst pressure rating, and 1,600 lb tensile strength for dependable service.
Compatible With 1969-1971 Mercury Montego, control valve end, and 1975-1976 Mercury Monarch, hydroboost to control valve (control valve end), w/ hydroboost, w/o skid control.
- Part number: 3401737
- Pressure hose assembly for power steering hydraulic routing
- 5/8 in. female end 1 and 1/2 in. male inverted flare end 2
- 32.6 in. overall length for application-specific routing
- CSM hose material for durability in steering service
- High-grade steel tubing with zinc electroplating for corrosion resistance
- High-pressure tested before leaving the factory
Application Details and Fitment
This Sunsong 3401737 hose is made for Mercury Montego and Mercury Monarch steering configurations listed above. It follows the original routing and connection style for the control valve end, helping maintain proper hydraulic pressure transfer in the power steering system.
This part cross-references Gates 355730 and Dayco 70679 for the same application.
What This Hose Helps Address
- Power steering fluid leaks at the pressure line
- Loss of steering assist from a damaged hose
- Corrosion-related hose or tube deterioration
- Incorrect fitment from a mismatched steering pressure line
- Hydraulic pressure loss at the control valve connection
Installation Notes and Tips
Verify end sizes, hose length, and routing before installation. This assembly does not include a bracket or power steering switch port, so confirm the vehicle’s original configuration matches the listed application. Inspect adjacent steering components, seals, and mounting points for wear before completing the repair.
Quality Assurance
Sunsong subjects each hose to high-pressure testing before it leaves the factory. The pressure hose construction is specified to exceed original equipment performance standards, with corrosion-resistant steel tubing and reinforced materials selected for long service life.
