Sunsong 3402154 Power Steering Pressure Line Hose Assembly - Pump To Hydroboost

Power Steering Pressure Hose for Hydroboost

Sunsong 3402154 is a power steering pressure line hose assembly for select Ford, Lincoln, and Mercury vehicles with hydroboost steering systems. It is built for direct-fit replacement on the pump-to-hydroboost circuit and is engineered to restore proper hydraulic pressure transfer in the steering system.

• Fits pump-to-hydroboost applications on select 1974-1976 Lincoln Continental, 1975-1976 Ford Thunderbird, 1975-1976 Mercury Grand Marquis, and 1975-1976 Mercury Marquis
• Also fits 1976 Ford LTD and 1976 Mercury Grand Marquis and Marquis with hydroboost, including listed notes for skid control and production date
• 5/8 in. male inverted flare fittings on both ends
• 50 in. hose length for the specified routing
• CSM hose material for pressure-line service
• Cross-references Gates 356770 for the same application

Built for Pressure-Line Service

This pressure hose assembly is made to exceed original equipment performance standards, with a 1,500 psi maximum working pressure, 8,700 psi burst pressure rating, and 1,600 lb tensile strength. The tubing is manufactured from high-grade steel with zinc electroplating to improve resistance to corrosion from humidity, road salt, water, and grime. Sunsong 3402154 is precision engineered for exact fitment on the pump-to-hydroboost route, helping maintain proper steering assist on vehicles such as the Ford LTD, Thunderbird, and Mercury Marquis.

Common Problems This Hose Can Address

• Pressure loss in the power steering circuit
• Fluid seepage or hose deterioration at the pressure line
• Corrosion-related failure on exposed steel tubing
• Incorrect routing or fitment from a worn original hose
• Reduced steering assist caused by a damaged pump-to-hydroboost line

Installation Notes and Tips

Verify the vehicle’s hydroboost configuration, production date, and any skid control notes before ordering. Match the 5/8 in. male inverted flare ends and confirm the 50 in. length against the original routing. This hose is intended for the pump-to-hydroboost position only, so compare the original line path and connection style before installation.

Quality Assurance

Each Sunsong pressure hose is high-pressure tested before it leaves the factory to help ensure proper operation after installation. The precision-fit design and corrosion-resistant steel tubing support reliable service in demanding steering applications.
