• Steering assist loss caused by pressure-line failure
• Incorrect fitment from a worn or mismatched replacement hose

Installation Notes and Quality Control

Verify the vehicle’s steering configuration, including hydroboost and front I-beam suspension details, before ordering. Confirm the 16 mm and 18 mm male O-ring connections match the original hose, and compare the 47.4 in. length to the removed part for routing accuracy. Every Sunsong hose is pressure tested before it leaves the factory to support trouble-free installation and operation. Part number 3402033 is also listed under Edelmann 91537 and Gates 364860 for the same application.

Quality Assurance

Sunsong pressure hoses are built to meet demanding steering-system service requirements and are tested under high pressure before shipment. The hose assembly uses corrosion-resistant steel tubing and exact-fit engineering to restore the original steering line configuration on the listed Chevrolet P30 and GMC P2500/P3500 applications.
