GM 25163684 Filter,Fuel

Release vehicle pressure in the fuel system and remove the negative cable from the battery terminal. Put the car in the air with jackstands and keep it stable. To disconnect the fuel line from the filter, use a flare-nut wrench on one side while an open-end wrench securely holds the hex part of the filter. To separate the quick-connect line from the filter, simply squeeze the plastic tabs with your finger and pull. When your car has quick-connect fittings, turn the connector clockwise and counterclockwise one-quarter turn to free stuck dirt, and use compressed air to blow out any remaining dust before separating the parts. Take off the filter, keeping track of whether your model uses a mount or not. Place the new filter in the clip or bracket and make sure it stays put while the arrows point toward the fuel heading toward the engine. Put a bead of clean engine oil on the male slot where the new filter will fit, then place the filter in its correct spot making sure the arrow points toward the engine. Attach the fuel line to the filter by putting fresh O-ring seals on top, and push the quick-connect fittings down until you hear a snap from the plastic pieces. Turn each female end of the quick-connect fitting by hand to make sure it locks in place before attaching the battery. Check to see if fuel is leaking by starting the engine by turning the key and leaving it in position On.
