Installation Notes and Tips
Verify the banjo and male O-ring end fittings match the original hose before installation. Inspect the mating surfaces, routing points, and nearby components for wear or contamination before replacing the line. Because this is a pressure-side hose, proper torque and clean sealing surfaces are important for leak-free operation.
Quality Assurance
Each Sunsong pressure hose is pressure tested before it leaves the factory to help ensure dependable installation and operation. The hose assembly is engineered to exceed original equipment performance standards for pressure, burst resistance, and tensile strength.
