Installation Guide

1. Safety First: Ensure the engine is turned off and has completely cooled down before beginning work.
2. Locate and Access: Identify the old exhaust tube hose connections on the engine and exhaust system.
3. Remove Old Hose: Loosen and remove the hose clamps securing the existing hose. Carefully twist and pull the old hose off its fittings.
4. Clean Surfaces: Thoroughly clean the mounting surfaces on the engine and exhaust fittings to ensure a good seal.
5. Install New Hose: Slide the new exhaust tube hose onto the fittings. Ensure it is fully seated and properly aligned.
6. Secure Clamps: Position four 5" hose clamps (not included) over the connection points and tighten them securely. Do not overtighten, as this can damage the hose.
7. Final Check: After installation, run the engine for a short period and check for any exhaust or water leaks around the connections. Re-tighten clamps if necessary.
