How Do You Clean A Fuel Filter?

Cleaning your fuel filter regularly is an important step in keeping your engine operating smoothly. Cleaning the fuel filter can help extend its life and increase the performance of other diesel engine parts and the complete fuel system.

 

Step 1: Remove The Fuel Filter

Turn off the engine and wait for the engine to cool down. Locate the fuel filter, usually in the engine area. It is recommended that you use a suitable tool to gently unscrew the nut holding the fuel filter.

 

Step 2: Clean The Fuel Filter

Use compressed air to purge the outer surface of the fuel filter to first remove large particles of impurities on the surface. Soak the fuel filter in clean diesel to ensure that the filter paper is thoroughly moistened. Use a soft brush to gently scrub the surface of the fuel filter, being careful not to damage the structure of the filter paper.

 

Step 3: Check The Fuel Filter

It is recommended that you carefully inspect the surface of the filter paper for obvious damage or holes. Next, check the inside of the fuel filter for accumulated sediment.

 

Step 4: Reinstall The Fuel Filter

Reinstall the clean fuel filter into its original position. Tighten the nut by hand, being careful not to overtighten to avoid damaging the filter. Start the engine with the starter motor and check if the fuel system is working properly.

 

How Do You Unclog A Fuel Filter?

When the fuel filter is severely clogged, simple cleaning cannot completely solve the problem. At this time, you need to consider unclogging the fuel filter. Unclogging the fuel filter requires some professional tools and skills.

 

Step 1: Remove The Fuel Filter

Before unclogging the fuel filter, turn off the engine to ensure that it has stopped running. Wearing protective glasses and gloves, remove the fuel filter.

 

Step 2: Use Unblocking Tools

Use a professional engine fuel filter unclogging tool and insert it into the inlet end of the engine fuel filter. Use your hand to push the unclogging tool deep inside the fuel filter to break up the accumulated impurities.

 

Step 3: Reverse Purge

Using compressed air, blow the fuel filter backward from where the unclogging tool was inserted. Use air to remove impurities from the fuel filter. Then reinstall the fuel filter and confirm that the fuel system is operating properly.

 

In routine maintenance, regular cleaning and unclogging of the fuel filter are steps to ensure long-lasting and stable engine operation. By taking good care of your fuel filters, we extend the life of your heavy-duty equipment.
