Detailed Description

Sunsong 3401964 is a power steering pressure line hose assembly for the Ford Mustang hydraulic steering system, specifically the pump-to-hydroboost connection used on 1997-1998 models. The hose is precision engineered to match the original routing and connection style, with 16 mm male O-ring fittings at both ends and a 37.5-inch overall length. This makes it a focused replacement for Mustang owners servicing the pressure side of the steering system.

Built with CSM hose material and steel tubing, this assembly is designed to handle demanding steering pressures while resisting corrosion from humidity, road salt, water, and grime. Sunsong part number 3401964 is also high-pressure tested before it leaves the factory to help ensure consistent operation after installation. This part cross-references Gates 365410 for the same application.

Common Problems This Part Can Address

• Power steering fluid leaks at the pressure line
• Cracked or deteriorated hose material
• Corroded steel tubing on the original line
• Hard steering caused by pressure loss in the hydraulic circuit
• Noise or fluid seepage from a worn pump-to-hydroboost hose

Installation Notes and Tips

Verify the vehicle is a 1997-1998 Ford Mustang with pump-to-hydroboost routing before ordering. Confirm both end fittings are 16 mm male O-ring and compare the hose length to the original line. Inspect the mating surfaces, O-ring seats, and nearby brackets or shields during service so the replacement line seals correctly and routes without contact points.

Quality Assurance

Sunsong pressure hoses are manufactured to exceed original equipment performance standards, and each hose is pressure tested before shipment to support trouble-free installation and operation. The steel tubing is zinc electroplated to improve resistance to corrosion and rust in harsh road conditions.
