Fuel filter put new one on , but is leaking

Try putting a new one on and it says to put a new fuel filter on,try the fuel filter first.

The fuel pump is designed to turn on for a couple of seconds and prime with the key on. This is normal. If there is an extended crank, the fuel pressure may be bleeding back into the tank through the check valve of the fuel pump or there is an injector leak/fuel pressure regulator leak causing the pressure to bleed off causing the extended crank. Install a fuel pressure gague and monitor the pressure to see if it bleeds off to 0. If it does, one of the afore mentioned is causing the problem

Recheck fittings on filter. Leak on side toward tank can be so small it does not leak fuel, but still sucks in air.

Well your engine has a carb, so it could be dirt in the carb, or a vac leak, or several other possible causes.
Does the choke close when the engine is first started ? Have you checked the fuel line to see if the pump is providing gas ?

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.

3

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.

FIRST RELIEF FUEL PRESSURE BY REMOVING GAS CAP REMOVE FUEL PUMP RELAY START ENGINE UNTIL IT DIES LACK OF FUEL. FUEL FILTER IS MOUNTED TO THE RIGHT FRAME RAIL.NEAR THE FUEL TANK.YOU NEED A FLARE NUT WRENCH TO LOOSEN FUEL LINE AT FILTER AND A ADJUSTABLE WRENCH HOLD FILTER LARGE NUT WHILE LOOSEN FUEL LINE THIS KEEP FROM TWISTING FUEL LINES WHILE LOOSEN FUEL LINE.BESURE TO GO TO DEALERSHIP AND BUY NEW O - RINGS AT FUEL FILTER LINES.LUBRICATE NEW O- RINGS WITH CLEAN ENGINE OIL.WHEN INSTALLING NEW FUEL FILTER DONT OVER TIGHTEN FUEL LINES CUTTINGTHE O -RINGS AT FUEL FILTER.IF SO THEY WILL LEAK GAS WHEN YOU START UP ENGINE.WHEN DONE CHECK FOR GAS LEAKS WHEN DONE DONT DRIVE UNTIL YOU CHECK FOR LEAKS FIRST.

FIRST OF ALL RELIEVE THE FUEL SYSTEM PRESSURE.RAISE AND SAFELY SUPPORT THE VECHICLE ON JACK STANDS.USING A BACKUP WRENCH REMOVE THE FUEL LINE FITTINGS FROM THE FUEL FILTER.FOR THE LINE DISCONNECT SIDE OF FUEL FILTER. SQUEEZE BOTH TAB IN. SO YOU CAN REMOVE FUEL LINE FROM FUEL FILTER.REMOVE THE FUEL FILTER MOUNTING SCREWS AND REMOVE THE FILTER FROM THE VECHICLE.REPLACE THE O RING WITH A NEW ONE LUBRICATE O RING WITH A LITTLE ENGINE OIL.TIGHTEN FUEL LINE TO FILTER CONNECTORS 22 FT LBS. THE 2.3L ENGINE RELIEF FUEL PRESSURE LOOSEN FILLER CAP.REMOVE FUEL PUMP FUSE LET ENGINE IDLE UNTIL IT DIES FROM LACK OF FUEL.THE 3.3L ENGINE RELIEF FUEL PRESSURE BY INSTALLING FUEL PRESSURE GAUGE TO THE FUEL PRESSURE TEST PORT WHICH IS THE SCHRAEDER VALVE WITH CAP.ITS ON THE FUEL PRESSURE REGULATOR ASSEMBLY.USE A SHOP TOWEL AROUND CONNECTION TO CATCH FUEL SPRAY.YOU CAN USE A SMALL TINY SCREW DRIVER AT PORT ALSO BUT COVER IT WITH TOWEL TO CATCH FUEL SPRAY.WARNING GO TO DEALERSHIP TO BUY O- RING THAT GOES ON THE FUEL LINE TO FUEL FILTER.IT LOOKS TAN.TAKE THE OLD O-RING TO GET THE CORRECT SIZE O- RING TO FUEL LINE TO FILTER.DONT USE ANY KIND O - RING GASOLINE WILL DISSOLVE IT YOU WILL HAVE A MASSIVE GAS LEAK.WHEN YOU FINISH PUTTING NEW FUEL FILTER IN PLACE ALL FUEL LINES CONNECTED.MAKE SURE WHEN YOU INSTALL NEW FUEL FILTER YOU HEAR OR FEEL THE DISCONNECT SNAP IN PLACE ON THE FUEL FILTER.PULL IT A LITTLE MAKE SURE ITS IN PLACE.WHEN ALL FINISH AND DONE.TURN IGNITION SWITCH ON POSITION ENGINE OFF 3 SECONDS CHECK FOR LEAKS.IF YOU GET LEAK FUEL LINE O - RING LEAKING BECAUSE TOO BIG TOO LOOSE OVER TIGHTEN DAMAGE O - RING.

You have a leak somewhere that is letting the fuel system **** in air. This is serious and needs to be taken care of immediately. Check all your lines and fittings for wet spots or signs of fuel leaking and repair. Also double check to make sure your new filter is on tight and no fittings have been put on crossthreaded. Hope this helps.

look under the car at the gas tank .look for small metal fuel lines that goes to a small little round metal canister that is mounted to a bracket with a bango fuel line connected to it.thats the fuel filter.FIRST RELIEVE FUEL PRESSURE BEFORE REMOVING FILTER.YOU LOOSEN GAS CAP.THEN YOU GET RAGS TO CATCH GAS THEN YOU GET INLINE WRENCHES.TAKE INLINE WRENCHES AND BARELY LOOSEN LINES AT THE FUEL FILTER TO RELIEVE GAS PRESSURE.USE RAGS TO CATCH GAS.WHEN YOU PUT THE NEW FILTER ON BESURE TO GET NEW BANJO WASHERS.DO NOT USE THE OLDS ONE ARE YOU WILL HAVE A GAS LEAKS.WHEN YOU FINISH REPLACING FUEL FILTER.TURN CAR IGNITION IN ON POSITION FOR A FEW SECONDS MAKE SURE YOU HAVE NO GAS LEAKS.

Replace the drain valve. They leak all the time.
