Moroso Holley Needles and Seats

5.0 out of 5 stars 2 Customer Reviews

Moroso Holley needles and seats are the parts you need for your Holley carburetor! Two versions are available—the Viton® needle design is highly recommended for gasoline fueled engines because it is resistant to dirt and conforms to the seat for superior sealing. If you use exotic fuels or additives such as alcohol, benzine, acetone, etc., you must use the steel-needle version. Select the needles and seats recommended for your application.
