first relieve the fuel pressure at the schrader valve. Use small plastic tool supplied with new filter to disconnect filter hose fitting at the fuel rail. Squeeze the tabs on the fitting and disconnect the fuel line from the filter, then remove the nuts and detach the filter. push the new disconnect fitting onto the new filter and lubricate both filter fittings weth clean engine oil. Install filter into bracket and puch the quick connect fitting onto the filter and fuel line, making sure they snap securely into place.
hello...follow these steps to replace fuel filter on your Grand Marquis:
1) Apply the parking brake. Unscrew the gas filler cap from the fuel tank on the driver's side. Open the hood and disconnect the negative cable from the battery
2) Go underneath the car from the driver's side. Look for the fuel filter mounted to the vehicle chassis just below the driver's seating area. You should be able to identify the fuel filter as a metal cylinder attached to a black hose. This hose is your fuel line and it should run from the fuel tank at the rear of the vehicle to the engine 3) Notice that the area between the fuel filter and the fuel line is covered by a set of push-connect fittings. Remove these fittings using a flat-head screwdriver. Simply slide the screwdriver between the legs of the clips and push outwards until the legs of the clips open up. Remove the push-connect fittings and set them aside. The fuel line should disconnect from the fuel filter when you remove the push-connect fittings. If the fuel line does not disconnect, pull on the fuel line until it detaches from the fuel filter.
3) Loosen the fuel filter retaining clamp that secures the filter to the chassis of the vehicle--- Slide the fuel filter out of the retaining clamp and discard it.
4) Slide a new fuel filter into the retaining clamp. Tighten the retaining clamp over the fuel filter to secure it to the chassis. Align the fuel line with the inlet and outlet lips of the fuel filter. Push the fuel line onto the fuel filter until you hear an audible click. Attach the push-connect fittings over the area where the fuel line and the fuel filter meet.
5) Reconnect the negative cable to the battery. Tighten the gas filler cap to the fuel tank. Turn on the ignition and allow the car to idle for a few minutes to pressurize the fueling system.
Visual check for leaks...that's it, you are done. Good luck & i hope this helps FixYa!
The "quick disconnect" fittings for the fuel lines are usually problematic to disconnect unless you use this tip. The fittings get full of dirt over time. First, use compressed air to blow out the dirt. Then spray the connection with penetrating oil. Now insert your disconnect tool and it will come apart much easier. It's also easier to disconnect all the hoses & electrical connectors after dropping the tank down about 6 to 12 inches. Below is a video which shows how to do this job. Do yourself a favor. When you re-install the tank, apply anti seize compound to the threads of the mounting bolts. That way, if you ever have to remove it again in the future, those bolts will come out easily.
Fuel Filter REMOVAL & INSTALLATION
Fig. 1: Remove the quick connect fitting from the filter
Fig. 2: Using a 21mm back-up wrench and a 16mm wrench on the line, loosen the feed line from the filter
Fig. 3: Carefully unthread the feed line from the filter and . . .
Fig. 4: . . . remove the filter from the retaining bracket by pulling the filter outward
NOTE: The vehicles covered in this manual are equipped with "Quick Connect'' fuel fittings. For more information regarding these fittings, please refer to Section 5 of this manual.
An inline filter can be found in the fuel feed line attached to the rear crossmember of the vehicle.
CAUTION Before disconnecting any component of the fuel system, refer to the fuel pressure release procedures found in Section 5.
Properly relieve the fuel system pressure as outlined in Section 5.
Raise and safely support the vehicle with jackstands.
Grasp the filter and nylon fuel line fitting on the tank-to-filter line. Twist the "quick-connect'' fitting 1?4 or a turn in each direction to loosen any dirt within the fitting. Use compressed air to blow out the dirt from the fittings at the end of the fuel filter.
Detach the quick-connect fitting by pushing inward toward the filter and grasping the plastic tab around the connector and pull apart. If additional assistance is required to disconnect the fitting, tool J 38778 or equivalent can be placed between the filter and the fitting release mechanism to carefully force the two apart. Be careful not to bend the special tool.
NOTE: Always use a back-up wrench anytime the fuel filter is removed or installed.
Using a backup wrench (where possible) to prevent overtorquing the lines or fittings, loosen and disconnect the feed line from the filter. Be sure to position a rag in order to catch any remaining fuel which may escape when the fittings are loosened.
Remove the fuel filter from the retaining bracket.
Before installing a new filter, apply a few drops of clean engine oil to the male tube end of the filter. This will ensure proper attachment and prevent a fuel leak.
Position the filter into the retaining bracket with the directional arrow facing away from the fuel tank, towards the throttle body.
NOTE: The filter has an arrow (fuel flow direction) on the side of the case, be sure to install it correctly in the system, with the arrow facing away from the fuel tank.
Push the connectors on the quick-connect fitting together to cause the retaining tabs/fingers to snap into place. Pull on both ends of the connection to be sure they are secure.
Connect the fuel feed line to the filter, then tighten, using a backup wrench to prevent damage, to 20-22 ft. lbs. (27-30 Nm).
Carefully lower the vehicle.
Connect the negative battery cable and tighten the fuel filler cap, then start the engine and check for leaks.
The Fuel Filter is located:
Under vehicle, driver side, below seating area,
driver side of fuel tank, mounted on frame in fuel
Here is the replacement procedure. Hope this helps Lefty64
Fuel supply lines on all vehicles equipped with fuel injected
engines will remain pressurized for long periods after engine shutdown.
The pressure must be relieved before servicing these fuel systems.
Disconnect the negative battery cable.
Depressurize the fuel system.
Remove the filter bracket retainer.
For plastic type fittings:
Grasp the filter and one fuel line fitting. Twist the quick connect fitting
turn in each direction to loosen any dirt within the fitting. Repeat for the other fuel line fitting.
Squeeze the plastic retainer release tabs and pull the connection apart. Repeat for the other fitting.
For metal type fittings:
Use a fuel pipe quick-connect separator J37088 or equivalent. This is available from your local parts store.
Insert the tool into the female side of the connector, then push inward to release locking tabs. Pull the connection apart.
Disconnect fuel tank hose at the fuel pump, and plug the hose with a bolt or wooden dowel to keep any fuel from flowing out wires. Check the hose and if it is frayed or cracked, replace it with new fuel line hose.
Disconnect the outlet line to the carburetor. Use a wrench on the fuel pump fitting and another on the line nut.
Remove the two attaching bolts and remove the old fuel pump. Clean off any old gasket material from the mounting surface of the engine.
Apply a coat of gasket sealer on both sides of the new gasket. Put the attaching bolts through the new pump and slip the gasket over the bolts.
Install the new pump on the engine. Make sure that the rocker arm in the pump is against the eccentric inside the engine, or that the push rod is correctly installed in both the engine and the fuel pump. If the push rod slides out, you can pack it with some heavy grease to hold it in place while you install the pump.
Attach the fuel outlet line that runs to the carburetor. If it's difficult to connect, remove the other end of the line from the carburetor. Connect the line to the fuel pump, and then reattach the other end to the carburetor. Use a wrench to hold the fuel pump fitting and tighten the line nut with another wrench.
Attach the fuel inlet hose from the gas tank, and the vapor return hose (if the vehicle is equipped with one). Tighten all clamps.
Reconnect the battery ground cable, start the vehicle and check for leaks.
