Description
SIERRA Aluminum Fuel/Water Separator Bracket, 3/8 in NPT – 18-7775 is an aluminum mounting head/bracket for Sierra spin-on fuel/water-separator systems using 3/8-inch NPT fuel ports. It provides the fixed fuel-in/fuel-out connection and threaded filter mounting point used in compatible separator assemblies.
This is the bracket only, allowing a damaged or corroded head to be replaced without buying a complete separator kit. Filter element, plugs and fuel fittings must be selected for the installation; confirm the thread size because Sierra also offers 1/4-inch head assemblies.
