Fuel filter location
The fuel filter in a 2007 Lincoln MKX is located on the left frame rail in front of the left rear tire. It is placed inside the top of the fuel tank, where it connects with the fuel line.
To replace the fuel filter, you must lower the fuel tank, although you don't have to drop it all the way. It is recommended that you do this with no more than a 1/4 tank of gas, as it makes the fuel tank lighter and easier to manage. You will then need to disconnect the gas straps from the car, giving you enough room to drop the tank.
The fuel filter will have a plastic clip in each fuel line that will be white in colour. Remove the clips, then disconnect the fuel line. Make sure to replace the clips and do not reuse the old ones. Install the new clips into the connector, then snap the connectors onto the new filter.
Many car companies recommend changing the fuel filter every 5 years/50,000 miles, but you may want to check it or have it cleaned more often depending on your driving habits and where you live.

Fuel filter maintenance
Fuel filters are essential components of a vehicle as they remove impurities that prevent your car from running smoothly. A clogged filter can lead to a "coughing" engine, and even a complete shutdown. Therefore, it is important to regularly maintain and replace your fuel filter.
The fuel filter is always located between the fuel tank and the engine, usually inside the top of the fuel tank, where it connects with the fuel line. However, in some cars, it might be located elsewhere along the fuel line. The fuel filter location for your specific model can be found in your vehicle manual or by asking a local mechanic.
To maintain good day-to-day performance, car companies recommend changing the fuel filter every 5 years/50,000 miles. However, this may vary depending on your driving habits and other factors. It is always a good idea to check your owner's manual for specific maintenance intervals.
If you notice any of the following symptoms, it may be an indication that your fuel filter needs changing:
- Problems with starting the engine
- Stalling, especially while idling at a red light or stop sign
- Excessive vibration while driving
- Rough slow-speed cruising
When changing your fuel filter, it is important to take the necessary precautions. Park your car in a level, well-ventilated area, and allow the engine to cool off. If you have a fuel-injection vehicle, depressurize your fuel system by opening the fuel filler cap and loosening it until you hear the pressure escaping. Then, locate and remove the fuel pump fuse or relay in your fuse box. Start the engine and pull out the fuse or relay—if the engine dies, you've pulled the correct one. Open the hood and disconnect the negative terminal on your car battery to prevent accidental sparks.
Next, find the fuel filter and determine how it is secured. It could be attached with clips, "banjo bolts", or other fasteners. Have a rag or towel ready, and use a screwdriver or wrench to detach the fuel line from the filter. Quickly plug the open fuel line with the rag to prevent any leaks. After that, remove the fuel filter by unscrewing the attaching bolts. Check the fuel lines, and if they appear frayed, you may need to replace them. Finally, install the new fuel filter, ensuring it is pointed in the same direction as the old one.

Symptoms of a clogged fuel filter
While fuel filters rarely clog, it is still important to be aware of the symptoms of a clogged fuel filter. A clogged fuel filter will almost certainly act the same way every time. If your car is hard to start sometimes, but not others, it is likely not the fuel filter. Once running after hard starting, if your car runs strong, it is probably not the fuel filter.
A partially clogged fuel filter may cause the vehicle to cut out when you try to pass someone or accelerate hard. It may also cause problems with starting, stalling, excessive vibration while driving, and rough slow-speed cruising. You may also notice a loss of power during hard acceleration, and the "Decreased Engine Power" warning light may come on. If you notice that your engine runs slightly hotter, this could also indicate a clogged fuel filter.
The main symptom of a clogged fuel filter will come when the fuel demand is highest, and will show up as an unexplained power drop, possibly followed by stumbling and rough running, or just quitting. When you ease up on the power, it should come back.
