Fuel Filter REMOVAL & INSTALLATION CAUTION
Never smoke when working around or near gasoline! Make sure that there is no igniting source near your work area! Fuel Injected Engines The fuel filter is of a one-piece construction which cannot be cleaned. If it becomes clogged, it must be removed and replaced. When replacing the fuel filter use the filter specified for the engine being serviced. The inline filter is mounted on the same bracket as the fuel supply pump. It is on the frame rail under passenger side of the vehicle, in front of the fuel tank. To replace the filter: Fig. 4: Whenever you see a warning label, read it 86651210.jpg
CAUTION
Fuel supply lines on fuel injected vehicles will remain pressurized for some time after the engine is shut off. Fuel pressure must be relieved before servicing the fuel system.

  1. Disconnect the negative battery cable.
  2. Relieve the fuel system pressure as follows:
    1. Remove the fuel tank cap to relieve any pressure in the fuel tank.
    2. Remove the cap from the Schrader valve located on the fuel injection supply manifold in the engine compartment.
    3. Attach fuel pressure gauge T80L–9974–A or equivalent, to the Schrader valve and drain the fuel through the drain tube into a suitable container.
    4. After the fuel system pressure is relieved, remove the fuel pressure gauge and install the cap on the Schrader valve.
  3. Raise and safely support the vehicle on jackstands.
  4. Disconnect the fittings from both ends of the fuel filter as follows:
    1. Inspect the visible portion of the fitting for dirt accumulation. If more than a light coating of dust is present, clean the fitting before disassembly.
    2. Some adhesion between the seals in the fitting and the filter will occur with time. To separate, twist the fitting on the filter, then push and pull the fitting until it moves freely on the filter.
    3. Remove the hairpin clip from the fitting by first bending and breaking the shipping tab. Next, spread the 2 clip legs by hand about 1⁄8 in. (3.1mm) each to disengage the body, then push the legs into the fitting. Lightly pull the triangular end of the clip and work it clear of the filter and fitting. NOTE: Do not use hand tools to complete this operation. Damage to the fittings may result.
    4. Grasp the fitting and pull in an axial direction to remove the fitting from the filter. Be careful on 90°elbow connectors, as excessive side loading could break the connector body.
    5. After disassembly, inspect the inside of the fitting for any internal parts such as O-rings and/or spacers that may have been dislodged from the fitting. Replace any damaged connector(s). Fig. 5: Carefully remove the hairpin clip 86651211.jpg
      Fig. 6: With a rag under the hose to catch any gasoline spillage, slowly separate the line from the filter 86651212.jpg

  5. If equipped, remove the filter retainer bolts and remove the filter and retainer from the mounting bracket. Remove the filter from the retainer. Note that the direction of the flow arrow on the fuel filter. Remove the rubber insulator rings, if installed. Inspect the rings for cracks or wear, and replace if needed. Fig. 7: Remove the hardware securing the filter to the housing 86651213.jpg
    Fig. 8: Lower the filter assembly, then separate the pieces 86651214.jpg
    To install:
  6. Install the fuel filter with the flow arrow facing the proper direction as before, then tighten the filter retaining clamp(s).
  7. If the original filter was equipped with rubber insulator rings, install the rubber insulator rings on the new filter. Install the filter into the retainer with the flow arrow pointing in the correct direction. Install the retainer on the bracket and tighten the mounting bolts to 27–44 inch lbs. (3–5 Nm).
  8. Connect the fittings at both ends of the fuel filter as follows:
    1. Install a new connector if damage was found. Insert a new clip into any 2 adjacent openings with the triangular portion pointing away from the fitting opening. Install the clip until the legs of the clip are locked on the outside of the body. Piloting with an index finger is necessary.
    2. Before installing the fitting on the filter, wipe the filter end with a clean cloth. Inspect the inside of the fitting to make sure it is free of dirt and/or obstructions.
    3. Apply a light coating of engine oil to the filter end. Align the fitting and filter axially and push the fitting onto the filter end. When the fitting is engaged, a definite click will be heard. Pull on the fitting to make sure it is fully engaged.
  9. Connect the negative battery cable. Start the engine and check for fuel leaks.
  10. Lower the vehicle.

How to replace fuel gauge on 1984 Grand Marquis


Are you sure its not the fuel sending unit and not the fuel gauge itself.Because the sending unit controls the fuel gauge level and if the float gets stuck then the fuel gauge will not work.

99 Grand Marquis Fuel Pump problem


Lets try a new keyswitch and a fuel filter. The key activates the starter side of the ignition. This terminal should power both the starter solenoid and the fuel pump. Although the fuelpump runs on the ignition side continuously, you should be primed when the key is in the "on" position. I would wonder if the pump is cutting off too early meeting the resistance of a dirty fuel filter.
