3. On injected cars the fuel system will remain pressurised even after the engine has stopped running , so its important not to undo anything until you know there is no fuel ready to mess up your day . To do this the easiest way is to remove the plug from the fuel pump found next to fuel tank . This means no power can get to pump , first slide out the pin before pulling out the plug . Once unplugged start car as normal and allow to stall ( runs out of fuel in about 10 -15 seconds ) . Try to restart to confirm no fuel , car will cough like its had a Marlbourgh , but won't start

Yeah , yeah I know you can remove the fuel pump relay or remove the engine control fuse from under the dash in fuse box.
Just make sure you are confident there is no residual pressure in system .

4. Time to remove filter , it will require a couple of spanners , so when you turn the one that is nearest the pipe the other remain still , its part of the filter . Avoid putting strain on pipes . You need to loosen both ends , then think about releasing screw bolt that secures filter to bracket . Even with no residual pressure in system , you can guarantee that some fuel will run down your arm and make you swear . Try very hard not to get it your eyes , that hurts

5. Once pipes and bracket have been released and filter has been removed , check that it matches the one you want to put in ( do you know how many silly billies work in parts shops ? ) . Check that when you replace the filter has the flow going in the correct direction , look for markings on filter itself .

6 . Reverse aforementioned procedure , not forgetting to replug power to fuel pump . Turn ignition , you can usually hear pump buzzing away refilling system , takes a couple of seconds , fire up your engine and let run for a couple of minutes . Then before putting car back on to terra firma check underneath to ensure no liquid gold is leaking .
7. Finally how often should you do this when filters cost $ 25- 40 , normally every 20,000 miles or so ( at least every 2 years )
