Built for Steering System Pressure

This Sunsong power steering cylinder line hose assembly is designed to replace the original hose on Mercury Colony Park and Mercury Marauder cylinder applications. Sunsong 3403334 is manufactured 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 steel tubing is zinc electroplated to help resist corrosion from humidity, road salt, water, and grime.

Common Problems It Can Help Solve

• Power steering fluid leaks at the cylinder line hose
• Cracked, hardened, or deteriorated hose material
• Corrosion on exposed steel tubing and fittings
• Steering pressure loss caused by a damaged line
• Fitment issues from an incorrect replacement hose

Installation Notes and Tips

Verify the vehicle year, model, and cylinder application before ordering. This hose assembly uses male inverted flare connections at both ends, so matching the fitting style and size is important for proper installation. Confirm routing, length, and clearance around the steering components before final tightening. Part number 3403334 is also listed as a cross-reference for Gates 352083.

Quality Assurance

Each hose is pressure tested before it leaves the factory to help ensure proper operation after installation. Sunsong also builds the assembly with required wear items and protective components as specified for the application, helping restore the steering line to original condition.
