Mercedes Engine Misfiring

The Leading Repair Shop in Pineville to Replace the Fuel Tank Screen Filter in a Mercedes

by Dutch Silverstein February 12, 2022

A fuel tank screen filter protects the fuel pump and the fuel line from dirt and debris. Large chunks of debris can damage your fuel line and fuel pump if the screen filter is damaged or not working correctly. This rubble can easily hit the underside of a car through everyday driving and travel. The fuel tank screen filter is usually made out of mesh, and it can be found within the Mercedes fuel tank.

Signs that Your Fuel Tank Screen Filter Needs to be Replaced

If you are unsure if there is a problem, you will want to be on the lookout for potential warning signs and symptoms. Here are the top 5 signs that your fuel tank screen filter needs to be replaced on your Mercedes.

  • Hesitation: You may notice that your vehicle does not seem to be running the way you are used to. One of those symptoms is any kind of hesitation you may feel from your engine. You may notice hesitation because dirt and debris did get into the system and it has caused lowered fuel pressure. Vehicles are impressive machines, but they require all parts and systems to operate at their top level to function the way you are used to your car driving.
  • Engine Misfiring: Another indicator could come when your engine misfires. You may only notice this when you are carrying a heavier weight than usual. The heavier the cargo, the more fuel is required to carry this load.
  • Poor Acceleration: When the fuel tank screen is damaged, this could also affect acceleration. Usually, this is only something you would notice during heavy acceleration, such as speeding up quickly to pass other vehicles or to merge onto a highway from a ramp.
  • Injector Issues: This is not an issue that you will see on every Mercedes, but you may if the model you own has a spring-loaded bypass valve. Spring-loaded bypass valves are great to help your vehicle deal with clogged filters. However, they can lead to the debris and dirt moving to the fuel injectors. If your vehicle has a spring-loaded bypass valve, it is essential to get regular maintenance to ensure there are no problems. If you are unsure, ask a trained vehicle technician who is certified in your Mercedes model.
  • Exhaust Fumes: Finally, you might also notice that the exhaust fumes your car is releasing are more than usual or that they smell a lot worse. If you determine that you’re having this issue, contact your mechanic immediately for an appointment.

How to Avoid Fuel Tank Filter Problems in the Future

Now that you understand the possible symptoms, you may also want to know how to avoid dealing with this particular problem in the future. Here are a few ideas to ensure you do not need emergency service on your fuel tank screen filter again.

  • Routine Inspections: Getting routine inspections is always a great idea for successful car ownership. Sometimes, when something is wrong with your vehicle, it is obvious. The symptoms of the problem could be screaming loudly at you to fix the problem. However, it is crucial to understand that this is not always the case. Some issues do not have obvious symptoms. By the time these problems are detected, the issue is a lot deeper and more expensive to repair than it could have been if your vehicle had regular inspections.
  • Regular Maintenance: Regular maintenance is also a good idea. Your owner’s manual will list a regular maintenance schedule recommended by the manufacturer. You should also be able to find your schedule on the internet at the Mercedes site as well. You can also ask our vehicle technicians about your maintenance schedule, as they are the experts on Mercedes models.
