On a 1991 Ford Thunderbird with a 5.0 V8, the fuel filter is on the bottom of the passenger floorboard just behind the front wheel. Turn the car on and open the trunk. Behind the carpet on the drivers side of the trunk, there is an inertial fuel cut-off switch. This is triggered if/when the car flips over or hits something really hard. Disengage this cut-off while the car is running. It will lower the pressure in the fuel line and the engine will die. Disconnect the battery under the hood. The fuel filter has a splash guard covering it. Remove the two bolts and un-fasten the quick-connects on either side of the filter. Save the two clips unless the new filter came with new ones. Remove the old filter put the new filter on and replace the retaining clips and the shield. Connect the battery, engage the inertial switch, and start 'er up. Should turn over for quite a few seconds until the fuel fills the filter and lines.

How do i use the fuel filter installation tool for 94 thunderbir

Be sure to relieve the fuel system pressure first.

Snap the tool over the fuel line and push it into the fitting to release the locking fingers.

Once both fittings are released grasp the fuel hoses, one at a time, and pull them straight off the filter.

Watch out for fuel spillage.
