Common Problems This Hose Can Address

• Cracked or split crankcase breather hose material
• Vacuum or vapor leaks in the emission control hose path
• Improper hose routing between the leak detection pump and canister
• Hardening or deterioration from heat and engine bay exposure
• Check engine concerns related to emission system hose failure

Installation Notes and Tips

Verify the hose path and end style before installation. The EMH161 uses push-in ends at both connections and a molded shape to match the original routing. Inspect adjoining fittings, canister connections, and the leak detection pump ports for wear or damage before installing the replacement hose. Confirm fitment by year, model, and emission hose location on the vehicle.
