Detailed Description

This Sunsong pressure hose is made for steering systems that require a direct hydroboost-to-gear connection. The 3402153 part number is designed around the original routing and connection points used on select Chevrolet G10, G20, and G30 as well as GMC G1500, G2500, and G3500 applications. It cross-references Gates 362330 for the same application.

For buyers searching for a 1990-1991 Chevrolet G20 power steering pressure line hose assembly or a GMC G2500 hydroboost to gear hose, this replacement provides the correct male O-ring end sizes and length needed for proper installation. Sunsong 3402153 is also a relevant choice for 1990-1991 Chevrolet G30 and GMC G3500 steering repairs where the original pressure line has worn, leaked, or corroded.

What It Helps Fix

• Power steering fluid leaks at the pressure line
• Cracked, hardened, or deteriorated hose material
• Corrosion on steel tubing from road salt, moisture, and grime
• Steering assist loss caused by a damaged hydroboost-to-gear line
• Noise or poor steering response related to pressure line failure

Installation Notes and Tips

Verify the vehicle’s hydroboost-to-gear routing before ordering, since this hose is specific to that configuration. Confirm the end fittings match the system: 16 mm male O-ring on one end and 18 mm male O-ring on the other. Check hose length and routing clearance around nearby components before final tightening.
