The aft inlet ring on the air filter housing had about 1/4" cut off and was cut back at an angle so that the 3" Scat tubing would fit properly. The Scat tubing was clamped to the air filter housing. The carb heat inlet was also trimmed back over 1/4. 2" Scat tubing was clamped to the carb heat muff and then the heat inlet.
