  • Fuel filter assembly with standpipe having valve element
    Patent number: 6171491
    Abstract: A fuel filter comprises a head (96) having an inlet (100) and an outlet (102). The head is connected to an element (266) by a nipple portion (186) which has a valve element (196) therein. An actuating projection (222, 272) is engageable with the valve element to open flow through said nipple portion when the correct element is attached thereto. The actuating projection is further supported on a central portion (220, 276) which prevents connection to a nipple portion that extends too far into the element. According to a further embodiment, the filter includes a housing (412) with a removable element (424) mounted therein. The housing has an inlet port (414) in direct fluid communication with a chamber (418). The outlet port (416) is in direct fluid communication with a central standpipe (422). The standpipe has a flow element (442) movable therein for controlling the condition of flow openings (436) in the standpipe.
