What This Hose Helps Address

• Power steering fluid leaks at the pressure line
• Loss of steering assist caused by a damaged hose
• Hydroboost brake assist issues related to pressure line failure
• Corrosion or rust on the original steel line
• Fitment problems from a worn or incorrect replacement hose

Installation Notes and Tips

Verify the vehicle uses hydroboost and a brake warning system before ordering. Confirm the 16 mm and 18 mm male O-ring connections match the original hose routing, and compare the pressure switch port location to the removed part. Because this is a pump-to-hydroboost pressure line, proper routing and secure sealing at both ends are important for steering and brake system performance.

Quality Assurance

Each Sunsong 3401833 hose is pressure tested at the factory before it leaves production. The hose assembly is engineered to exact fit requirements for the listed Chevrolet Express and GMC Savana applications, helping support trouble-free installation and operation.
