  • Patent number: 5853575
    Abstract: A remote fuel filter kit that maintains the prime on a fuel system while changing the engine fuel filter or when the engine is off. A filter adapter is installed on the engine in place of the original fuel filter. The adapter directs the fuel from the engine to a remote filter attached to a remote filter head, and from the remote filter back to the engine. The remote filter head can be mounted in any assessable location and will accept the original fuel filter. The remote filter head has at least one check valve located in the passage from the engine to the remote filter head. The check valve prevents air from being admitted into the fuel system when the fuel filter is changed or during engine-off situations. Fuel hoses, mounting brackets and installation hardware complete the remote fuel filter kit.
