How To Change Diesel Fuel Filter

The diesel fuel filter ensures clean fuel before reaching the injectors supplying the engine. If a filter is dirty or clogged, you may find it difficult to start your car or you may notice it idling roughly, possibly the sound is ready to stop. Most diesel engines have two fuel filters: The primary filter is found somewhere in the fuel line between the fuel tank and the engine, while the secondary filter is usually located near the engine. Before the colder weather settles down, you should change both filters.

Here’s how to replace your diesel fuel filter:

Locate the main fuel filter. The first fuel filter will be on the fuel line and should be underneath the vehicle. Place an oil drain pan directly below the filter. With the appropriate tool in hand – usually an Allen wrench or hexagon tool – remove the plug from the fuel filter and let the fuel drain into the pan. Once the water is completely drained, secure the plug in its correct position.

Remove the primary fuel filter. Next, remove the first fuel filter, using a wrench and socket to loosen the cap. Once removed, extract the filter from its housing. Locate the O-ring on the lid, using a flat-head screwdriver to separate it. Throw away the old washer as the new filter will come with one.

Install a new fuel filter. Before installing the new fuel filter, use a clean cloth to wipe the inside of the housing and around the sealing surface. Next, place the new ring on the cap and secure it in place. Place the new filter inside the cap, then secure both sides inside the housing. Tighten by hand, then finish tightening with a torque wrench.

Replace the secondary fuel filter. The secondary fuel filter can be found next to the engine. Move the drain pan directly below the plug and repeat steps 1 to 3.

Dispose of old fuel filters and diesel fuel properly. Never dump old diesel fuel down the drain or dispose of it in the trash. There are several places to recycle diesel fuel, depending on what’s available in your area – your municipality may have a suitable recycling center. Once you’ve finished cleaning, update your maintenance records to show the date and distance traveled when the job was completed, so you know when it needs to be done again.
