  "textContent": "A fuel filter for a vehicle has a filter head delimiting an inlet port and an outlet port, a filter housing which is to be screwed below the filter head and which contains a filter element centred on a central axis. The filter element includes a filter medium, a top end plate and a bottom end plate. The filter housing delimits a first volume for receiving a flow of liquid to be filtered, the first volume being delimited radially around the filter medium and communicating with the inlet port and a second volume for receiving a flow of filtered liquid, the second volume being delimited radially inside the filter medium and communicating with the outlet port. The filter head includes an anti-leakage valve with a closing element that is movable between a closed position in which it closes off the inlet port and an open position in which the liquid can flow through the inlet port. The filter includes a pin that is fitted on the filter element to penetrate inside the inlet port so as to move the closing element from the closed position to the open position.",
