If the engine in your car, SUV, van, or crossover is beginning to sputter, the chances are great that your factory-installed fuel pump is beginning to go bad and needs replacing. That's why it's one of the most important components in your Mercedes-Benz vehicle's fuel system, and one that needs to be checked on a regular basis.

Depending on your vehicle's age, the fuel pump may depend on the engine to create suction that pushes fuel through the system. Newer models feature a DC motor that helps power things, putting less of a load on the engine.

In addition to a sputtering engine, other signs of a faulty fuel pump include worsening fuel efficiency, trouble starting your vehicle, squealing noises coming from under the hood, and a lit "Check Engine" dash light -- though the last two can be due to many issues, meaning you'll need to connect a code reader to find out the source of your trouble.
