What It Helps Address

• Leaking or cracked power steering return hose
• Soft hose sections caused by age and heat exposure
• Incorrect hose length when replacing bulk return line sections
• Return-side steering fluid seepage at cut-to-fit repairs
• Service needs on classic Chevrolet and GMC steering systems

Installation Notes and Tips

Measure the original routing before cutting the hose to length. Verify the 3/4 in. inside diameter matches the existing return line connections and confirm whether the vehicle uses a remote reservoir configuration where noted in the fitment data. Because this is a bulk return hose, final fit depends on accurate measurement and proper routing away from heat and moving components.

Quality Assurance

Sunsong states that its return hoses exceed original equipment performance standards and are rated for a maximum working pressure of 250 psi. The hose is intended for low-pressure, high-temperature return-line service in steering systems.
