The fuel filter purpose is to provide the fuel injectors with the proper amount of fuel and proper pressure for complete combustion. The parts of the fuel system include the fuel pump, fuel pump relay, fuel filter, fuel pressure regulator and gas tank. Some fuel pump problems include failure to start and can include a blocked fuel line, clogged fuel filter, bad fuel pump fuse, defective fuel pump relay, any of a number of electrical faults with the fuel wiring, bad fuel pump, possibly fuel levels read incorrectly by the ECM, even the anti-theft system miss-sending info and disabling the fuel pump. Sometimes the fuel pressure regulator doesn’t allow the fuel pump to provide enough pressure to the fuel injectors.
For the home mechanic, an easy way to check whether the fuel pump is the problem is to turn the key to the “on” position and listen for the fuel pump noise. It may take a few times to recognize the sound, but a quiet running noise should be apparent. If you hear the fuel pump running, then it is likely another problem. If you can’t hear any running noise, then it is likely the fuel pump isn’t working. Have someone else check with you to be sure. Once you figure out what is going on with the pump, it is easier to decide what to do. Symptoms of a clogged fuel filter include hard starting. When driving there may be reduced performance issues such as when driving at highway speeds or accelerating. A clogged fuel filter can be noisy making buzzing noises quietly at first and as they fail the noise usually gets louder. Another problem can be stalling or even hesitation, which can be dangerous anytime. A clogged fuel filter may eventually cause the failure of the fuel pump. Sometimes the filter is separate and sometimes this filter is attached to the fuel pump.
A bad fuel pump relay can show up as a loss of power while driving or can even shut down. Difficulty with the engine making grinding noises when trying to start the engine can also be a bad relay. Most fuel pumps are located inside the gas tank so that the fuel can keep the pump cool and lubricated. Other possible locations are on the underside near the gas tank or near the frame of the vehicle. Some Mercedes have two fuel pumps with one pump located in the gas tank and the other on the underside of the vehicle. There is a strainer at the fuel pump inlet that filters the gasoline and contaminants before going through the pump. This inlet strainer can sometimes get clogged.
Symptoms of a diesel fuel pump failing include difficulty accelerating, and low fuel pressure which shows up in starting the vehicle. If there is not enough pressure and fuel for the fuel injectors, it may need repeated tries starting until it starts and keeps running. It is also common that the fuel pump makes a lot of high pitched noises, or sometimes described as a scraping noise, or even a whistling noises before the fuel pump goes down completely. It’s best to have it checked out as soon as possible. The recommended schedule for the diesel fuel filter change is 30K miles for both the main filter and pre-filter. The main filter also functions as a water separator and can only hold a small amount at a time.
This water can freeze right in the main filter and can cause no starting problems and poor running condition. However, if your fuel tank has accumulated lots of water it will spill over the main fuel filter and be taken in as fuel by the engine causing rough idling and rough running conditions. The water can cause the injectors and the injection pump to fail. If there is a buildup of microbial and fungi bloom including bacteria in the pre-filter, they eat and thrive on the diesel fuel. Treatment from a biocide (available at a marine store) is necessary to kill the bloom off and also use a de-watering additive to rid the water from the tank. The pre-filters will need multiple cleanings till the bloom has died out.
Prevention recommendations are to change the fuel filter every 30K miles unless it needs changing earlier. Don’t’ run the tank empty, it’s hard on the fuel pump and will vacuum up debris from the bottom of the fuel tank and clog it up. Linear Automotive only uses recommended factory OEM parts and fluids in their repairs and services.
