What You'll Learn
Locating the fuel filter
Once the air filter is removed, the fuel filter can be disconnected by squeezing the clips with your fingers and sliding them a few centimetres further up the hose, away from the filter. This ensures that the clips stay attached and do not fall into the engine bay. With the clips moved, the hose can be slid off the metal pipe. It is important to have some kitchen roll or a rag ready to catch any spillage from the hoses.
With the hoses disconnected, the bolt holding the fuel filter to the bracket can be unscrewed using a 10mm socket or spanner. The cable can then be unhooked from the bracket by sliding it horizontally and then dropping it down.
Some people may choose to replace the fuel filter with a new one, while others may opt to clean or repair the existing filter. This can involve cutting the old filter and removing it, and then securing a new filter in a more convenient location.

Disconnecting the hoses
To disconnect the hoses, squeeze the clips with your fingers and slide them a few centimetres further up the hose, away from the filter. This way, they stay attached and you have no risk of losing them into the engine bay. Now, slide the hose off the metal pipe. Have some kitchen roll or a rag ready, as you will get some spillage out of some of the hoses.
With the hoses disconnected, unscrew the bolt holding the fuel filter to the bracket using a 10mm socket or spanner. Unhook the cable from the bracket by sliding it horizontally and then dropping it down.
Now, with the hose still off and a rag over the end of the metal pipe, pump the black plunger. Pumping could take a couple of minutes, so keep at it. The plunger will begin to go hard and the fuel will begin to flow out of the open pipe. Stop pumping and reconnect the hose. Pump a little more to continue to push the diesel through. The plunger will become quite firm.
Remember to refit your air filter and the plastic trim directly above the filter before attempting to start the car.
