1. Prepare the new fuel filter, take care that it cannot wear chemical fiber when operation so that it can avoid static

2. In order to avoid oil injection or fire accident when tear down filters, it needs to release the pressure in the fuel system before cutting the fuel pipe. When replacing the fuel filter, it is better to proceed in refrigerator car. At this time, the oil pressure is relatively low in the fuel system, the gasoline that flows out is relatively little when tear down the filters

3. Find the location of the fuel filter and pull the fuel filter out from the installing bracket. Place the cup under the oil pipe and then use the pliers to tear down the single use band

4. Pull the tube that in the oil inlet of the diesel filter out, at this time he fuel will overflow from the pipe and then lead the fuel to the cup. When the rate of flow become little, it needs to put band and connect the oil inlet of the new filter as soon as possible and block the other connector temporaily. At the same time, it needs to block the oil inlet of the old filter

 5. Pull out the other side of the old filter and connect the new filter. Use the screwdriver to tighten the band and avoid oil leakage. Install the new filter to the original place.

 6. Start the truck and idling for a while, check whether there is any oil leakage in the fuel filter connection

If it finds filter pipe has aging or crack that caused by dust or oil, it needs to replace this pipe at the same time to confirm the traffic safety.
