Route high-pressure power steering fluid from the pump to the steering gear with the Sunsong Power Steering Pressure Line Hose Assembly 3402508. If a cracked or leaking pressure line is behind fluid loss or steering whine, this direct-fit replacement for the 2003-2006 Toyota Tundra replaces it — see the Buyer's Guide tab for the engine-specific applications.
- Pre-assembled with brackets: the hose ships with its brackets already attached for easier installation and reduced labor time versus replacements sold as individual hoses.
- Precision engineered: built to an exact fit and includes the additional components needed so the wearable parts are restored to original condition.
- High-pressure construction: the pressure hose carries a max working pressure of 1,500 psi, a burst rating of 8,700 psi, and 1,600 lb tensile strength for durability and long life.
- Factory tested: every pressure hose passes a high-pressure quality-assurance test before leaving the factory for trouble-free installation and operation.
