2. Depressurize the fuel system.
3. Remove the filter bracket retainer.

   1. Grasp the filter and one fuel line fitting. Twist the quick connect fitting 1⁄4 turn in each direction to loosen any dirt within the fitting. Repeat for the other fuel line fitting.
   2. Squeeze the plastic retainer release tabs and pull the connection apart. Repeat for the other fitting.
