Description
SIERRA 30-Micron Carburetor Fuel Filter – 18-7859 is a 30-micron replacement fuel filter for many older marine carbureted engines, including GM inline four- and six-cylinder engines, Ford and GM V8s up to the specified power range, and MerCruiser 224 CID applications.
This element belongs to the older carburetor/fuel-pump filtration systems rather than modern spin-on water separators. Match the OEM filter number and pump/carburetor arrangement before installation so the correct element style is used.
