Relieve the pressure in the fuel system by first removing the engine compartment relay panel cover on the left side. Then, remove the fuel pump relay from the relay pane and start the engine. Let it idle until it stalls, and then crank the engine for about 5 seconds to make sure the pressure was released. Turn the ignition off.
Disconnect the negative battery cable. Raise and support the Mercury Villager. Remove the fuel hose clamps, and then disconnect and plug the hoses to prevent them from leaking fuel. Take the fuel filter out of the bracket.
Install the new filter in the bracket with the arrow pointing toward the engin in direction that fuel flows through the system. Connect the fuel hoses to the new filter. Put on the hose clamps and tighten them. Make sure they are properly tightened so there are no fuel leaks, and that pressure is maintained at about 36 in-lbs.
Lower the vehicle and reconnect the negative battery cable. Start the engine of your Mercury Villager, and check for leaks. Make repairs if necessary.
