What You'll Learn
Locating the fuel filter

Depressurising the fuel system
Before you start replacing the fuel filter, you must relieve the pressure in the fuel system to prevent fuel from spraying out when you remove the old filter. To do this, locate the fuel pump fuse or relay in the fuse box and remove it. Then, start the engine and let it run until it stalls. This will depressurise the fuel system. You should be prepared for fuel to leak out of the lines when you remove them, so have a rag handy to catch any spills.
Once the fuel system has been depressurised, you can then move on to the next steps of replacing the fuel filter. This will involve disconnecting the fuel lines from the old filter, removing the old filter, and then connecting the fuel lines to the new filter. You will then need to turn the ignition key to the 'on' position, but do not start the engine. This will allow the fuel pump to pressurise the fuel system. Check for any leaks around the fuel filter and fittings. If you see any leaks, tighten the fittings until the leaks stop.
You should then dispose of the old fuel filter properly and clean up any spilled fuel with a rag. Finally, you will need to reinstall the fuel pump fuse or relay that you disconnected earlier. Try starting the vehicle. If it runs normally and there’s no fuel leaking from the new filter, the job is done.

Disconnecting the fuel lines
There are various types of fuel line connectors, and the method for disconnecting them varies. For a push-type connector, you might need to push from both directions to release it, or you might simply push it down and pull it off. For a push-and-lock style connector, push it onto your fitting, then push the locking tab through. A pinch-type connector has retainers on each side that you pinch together to disconnect. For a horseshoe-type fitting, use a screwdriver to pull the horseshoe up and out.
Beneath the fitting, there’s a safety line. To remove this type, release the safety latch and push the connector back through. If you don't have a special tool, you can slip the open-ended clamp down the fuel line to the connector and push it into the connector, which will push apart the spring inside. Be prepared for fuel to leak out of the lines when you remove them, so have a rag handy to catch any spills.

Installing the new fuel filter
To install the new fuel filter, first locate the fuel pump fuse or relay in the fuse box and remove it. Then, start the engine and let it run until it stalls. This will depressurise the fuel system.
Next, use a wrench or pliers to loosen the fittings on both sides of the old fuel filter. Be prepared for fuel to leak out of the lines when you remove them, so have a rag handy to catch any spills.
Now, install the new fuel filter in the same position as the old one. Make sure the arrow on the fuel filter points towards the engine, as this indicates the direction of fuel flow. Tighten the fittings on both sides of the fuel filter to secure it in place.
Finally, turn the ignition key to the "on" position, but do not start the engine. This will allow the fuel pump to pressurise the fuel system. Check for any leaks around the fuel filter and fittings. If you see any leaks, tighten the fittings until the leaks stop.
