This is the tube that comes off the bottom of the carb? Needs to run between the engine and trans to the bottom of the frame so it drains onto the ground. On my 325 engines it will run from the carb to the front of the engine and down behind the clutch cover to the bottom of the frame. Doesn't really matter where it runs as long as it doesn't get melted and goes past the bottom of the frame. Keep it away from moving parts and excessive heat.
