Detailed Description

Sunsong 3402103 is a replacement power steering pressure hose assembly for 1968 Buick Skylark and 1969-1970 Buick LeSabre. The hose is built to restore pressure-side steering fluid flow with the correct end fittings and length for the listed applications. This part number, 3402103, is intended for buyers searching for a Buick Skylark power steering pressure hose or a Buick LeSabre pressure line hose replacement with OE-style fitment.

The assembly uses high-grade steel tubing with zinc coating to resist rust and corrosion from humidity, road salt, water, and grime. Its pressure ratings and reinforced construction support long-term service in demanding steering systems. If you are replacing a worn or leaking pressure hose on a 1968 Buick Skylark or 1969-1970 Buick LeSabre, Sunsong 3402103 provides a direct replacement path with the correct inverted flare connections.

This part cross-references Gates 352600 for the same application.

What It Helps Fix

• Power steering fluid leaks from a cracked or worn pressure hose
• Hard steering caused by pressure loss in the steering circuit
• Noise or hesitation from restricted fluid delivery
• Corrosion-related hose failure on older Buick steering systems
• Incorrect fitment from a mismatched replacement hose

Installation Notes and Tips

Verify end fitting sizes before installation: 5/8 in. male inverted flare on one end and 11/16 in. male inverted flare on the other. Confirm hose routing, clearance, and overall length against the original part before tightening connections. Because this assembly is application-specific, it is important to match the vehicle year and model exactly for 1968 Buick Skylark and 1969-1970 Buick LeSabre service.

Quality Assurance

Each Sunsong pressure hose is pressure-tested before it leaves the factory to confirm proper operation. The hose assembly is engineered to exceed original equipment performance standards in pressure capacity and durability, with corrosion-resistant tubing for extended service life.
