Abstract
A fuel filter comprises a head (96) having an inlet (100) and an outlet (102). The head is connection to an element (266) by a nipple portion (186) which has a valve element (196) therein. An actuating projection (222, 272) is engageable with said valve element to open flow through said nipple portion when the correct element is attached hereto. 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. The cover further includes a cover projection (482) for supporting a projection (478) on end cap (460) of the filter element, which opens flow into the standpipe only when the element is installed.
