The fuel filters in your BMW car or SAV work just like the others in your vehicle, in that they protect the engine and important parts from contamination. Much as the oil filter strains those pollutants out of the motor oil that lubricates the engine parts, the fuel filter removes particulates from the gasoline that feeds combustion. Since your vehicle also uses an air filter to prevent airborne irritants from getting into the motor, your engine is capable of running at peak performance. Even better, these filters help to prevent having to pay the sizeable cost of an engine repair.

How Fuel Filters Work

Most fuel filters are located just inside the fuel tank. It's a cylindrical cartridge that's filled with filter paper, and collects impurities, rust, dirt, and more before they can make their way along the fuel lines and into the fuel system. However, even the best fuel filter will eventually get clogged up. When that happens, you'll want to replace it as soon as you can.

How to Spot Fuel Filter Problems

Signs of a failing fuel filter include:

Lag in engine response

Repeated engine stalls

Your engine starts roughly

You can't start your engine at all
