Detailed Description
Sunsong 3401799 is a power steering pressure line hose assembly made for Acura TL models from 1999 through 2003. It is engineered to meet demanding steering system requirements with a maximum working pressure of 1,500 psi, a burst pressure rating of 8,700 psi, and tensile strength of 1,600 lb. The steel tubing is zinc-coated to resist rust and corrosion from humidity, road salt, water, and grime, while the CSM hose material supports long-term fluid handling in the steering circuit. This part cross-references Edelmann 92154 and Gates 365532 for the same application.
Common Problems This Part Can Address
- Power steering fluid leaks from a worn or damaged pressure hose
- Hard steering caused by pressure loss in the hydraulic line
- Noise or inconsistent steering assist related to hose deterioration
- Corrosion on the original steel line from road exposure
- Fitment issues when replacing a failed Acura TL steering pressure line
Installation Notes and Tips
Verify the 12 mm and 18 mm male captive O-ring fittings match the vehicle connection points before installation. Confirm the PS switch port routing and hose length against the original line on the 1999-2003 Acura TL. Inspect surrounding brackets, seals, and mounting points for wear so the replacement hose seats correctly and the steering system can be refilled and bled properly after installation.
Quality Assurance
Each Sunsong 3401799 hose is pressure tested at the factory before it leaves production. The assembly is precision engineered for exact fitment and built to restore the steering line to original-condition operation on the Acura TL.
