The type of fuel filter used in a Murray riding mower can vary depending on the specific model and year of manufacture. However, many Murray riding mowers typically use a 1/4-inch inline fuel filter. This type of filter is typically made of plastic and has a small cylindrical shape with two barbed fittings on either side for attaching to the fuel line. The filter element inside is usually made of a porous material such as paper or felt that traps dirt, debris, and other contaminants from the fuel.
To find the correct fuel filter for your Murray riding mower, it's recommended to refer to the owner's manual or parts diagram for your specific model. You can also consult with a knowledgeable staff member at a local hardware store or lawn equipment dealership to ensure you get the right fuel filter for your mower.
