Detailed Description
Sunsong 3401539 is a replacement power steering pressure hose assembly for Ford F-250 and Ford F-350 trucks that use a hydroboost-to-gear configuration. It is specified for 1988-1989 Ford F-250 and F-350, and for 1997 Ford F-250 HD and F-350 models noted as to 8/10 with flared fitting. This hose assembly is built with exact-fit engineering to restore the pressure line path and maintain proper steering system operation. The part number 3401539 is also referenced in aftermarket cross listings for the same application.
The construction uses high-grade steel tubing with zinc coating to resist rust and corrosion from humidity, road salt, water, and grime. Sunsong states the hose exceeds OE performance standards with a 1,500 psi maximum working pressure, 8,700 psi burst pressure rating, and 1,600 lb tensile strength. This part cross-references Gates 365930 and Dayco 71416 for the same application.
What It Helps Address
- Power steering fluid leaks at the pressure line
- Cracked, corroded, or fatigued hose sections
- Loss of steering assist from pressure-line failure
- Improper fitment on hydroboost-to-gear Ford steering layouts
- Noisy or inconsistent steering operation caused by a damaged hose
Installation Notes and Tips
Verify the fitting types before installation: 1/2 in. male inverted flare on one end and 5/8 in. male O-ring on the other. Confirm the vehicle uses the listed hydroboost-to-gear routing and match the application notes for 1997 Ford F-250 HD and F-350 models. Inspect mating surfaces, routing clearance, and adjacent components before tightening the connections.
Quality Assurance
Each Sunsong 3401539 hose is pressure tested at the factory before release to help ensure proper operation after installation. The hose assembly is engineered to restore original-condition wear components where applicable and to provide consistent service in the listed Ford applications.
