Fuel filter on my '95 Thunderbird LX 4.6L. Filter is located on passenger side frame rail just behind the front wheel well.
For removal, first purge residual fuel pressure at the schrader valve located on fuel rail, by pressing the pin down with a small screwdriver. Engine Off. Key Off. There is a cap that unscrews from the valve, and use a rag, and cover the valve while purging the system to avoid the spray of gasoline.
The are two 8mm bolts holding the shield in place. Use anti-seize compound on the threads upon re-instillation for ease of removal in the future. The worm gear clamp holds the filter canister to the shield.
Once the shield is dropped remove the retaining clip from the inlet side (tank side) of the line connector using a small flat tipped screwdriver, and pull apart. Caution: Gas will pour out of the line from the force of gravity so use a container to catch the gas, and keep the line up while conducting the remove, and renew procedure.
Once that line is detached loosen the worm gear clamp, and slide the shield back, remove, and set aside.
Next remove the retaining clip from the outlet side (engine side) of the fuel filter connector. If so equipped.
Use a quick disconnect tool to remove this line by placing the right size tool around the line, and pressing it into the connector, and gently pull the line from the filter.
Reverse order to install. Make sure the filter is installed in the right direction. There is an arrow on must filters that shows the proper direction of fuel flow. And/or marked "inlet/outlet".
You don't need the quick disconnect tool to install the outlet line, just push it together until you feel/hear a positive coupling of components. As with both lines, once they are together try to pull them apart gently to make sure they a fitted correctly.
Once everything is back together turn the key to the On position, and check for leaks.
