Having a clean fuel filter is important for the longevity of your engine. It helps keep your fuel system clean and ensures the delivery of pure fuel to the engine's injectors. A dirty filter can cause engine trouble and a rough idle.

There are several different types of fuel filters available, from the bowl-like type to the high-tech cartridge style. Some of them are even fitted to the fuel pump.

There are many reasons to change your fuel filter, but the obvious reason is to keep your engine clean. Unfiltered fuel is a breeding ground for contaminants, which can to decreased fuel flow, poor engine performance and a failure of your fuel pump.

Changing your fuel filter is relatively easy, provided you have the tools and know what you're doing. A professional auto repair shop should be able to replace your filter in no time. Depending on your car, you may only need to do the job once every 30,000 miles or so.

A clean fuel filter can also prevent clogging, which can result in engine performance issues. The way to tell if your fuel filter is clogged is to check for leaks. You should also check your fuel pressure before starting the engine. If you don't find a leak, your engine may not start.

The way to determine the fuel filter for your vehicle is to check your manufacturer's recommended maintenance schedule. If your car isn't on the list, you can get a replacement filter from a local auto parts store.
