6) Fuel Filter - Removal
Using a flat head screw driver or pliers, loosen the 3 clamps attached to the fuel pipes. This may take a while.
The clamps indicated in the photo should be loosened, rather than removed.
Once the clamps are loosened, remove the 4 fuel pipes from the Fuel Filter. The method I chose was to loosen the 3 clamps and then loosen the thick small rubber pipe extensions by sticking a screw driver in/under them and forcing them off the Fuel Filter. Trust me, this step will really test your patience!
Once you remove the Fuel Filter, you may get up to 1 litre of fuel still drip form the fuel pipes. It is advisable to catch that in a pan, so it does not spill on the floor and be a hazard. Also, do have a second person with a fire extinguisher waiting by you. When the Fuel Filter is being removed, do be careful that no fuel gets in your eyes.
Just for information as to what hose / pipe is for what:
1- Fuel Return
2 - From Fuel Tank
3 - Regulator Vacuum Hose
4 - Fuel Supply to Injectors
7) Swapping The Fuel Filter
Fit the new Fuel Filter, ensuring the rubber hoses and more importantly the clamps are tight.
8) Re-assembly
Now work in reverse order following all the above steps.
9) Final Steps
Once you have fitted the fuse back in, turn the ignition key to #2 and wait for 10 seconds, may be press the accelerator too. This will ge the fuel back in the fuel lines. I was able to start the car the first time with out any issues. Press the accelerator a few times to ensure the fuel is flowing smoothly.
Once the car is started, check for any leaks from the Fuel Filter.
