How to Replace a Fuel Filter on a 1990 Lincoln Town Car
The fuel system on a car contains at least three main components: a fuel pump, a fuel injector and a fuel filter. Changing the fuel filter is a simple procedure that usually takes about 30 minutes to complete. The fuel filter helps clean the fuel before sending it to the fuel injector. Over time, your fuel filter can become clogged, potentially causing major damage to your engine. To prevent this, you should change your fuel filter about every 25,000 miles.

Locate the gas tank on the passenger side of the car and unscrew the fuel tank cap. Leave the fuel tank cap unscrewed.
