Replacing the Fuel Filter(Corsa B 93+)
This Tutorial is split into two sections, Part A explains how to depressurise the fuel system whilst Part B explains how to replace the Fuel Filter.
Tools and Parts needed:
A selection of Star Head "bits"
Flat blade screwdriver
Needle Nose Pliers
Small tray to catch fuel in
Plenty of Paper Towel
Part A: Depressurising the Fuel System
Underneath the drivers side footwell near where the bonnet release lever is undo the screws as shown in red circles in the below picture.
Locate the plastic cover over the screw holding the trim as shown on the below picture, prise off the plastic cap and undo the star head bolt underneath.
Remove the plastic trim (you may need to pull off the weatherstrip slightly) to reveal the fuel pump relay switch, see below image. Pull the relay (purple on my car) out of its socket and run the car for 5 seconds.
You have now depressurised the fuel system.
Put the relay back in and any plastic trims you have removed.
If you intend to replace the fuel filter DO NOT turn the key in the ignition as this will pressurise the fuel system again
Part B: Replacing the Fuel Filter
The fuel filter is located on the vehicle as shown here. Just underneath the Sill.
The Fuel filter looks like this.
Undo the nut as shown by the red circle, the fuel filter will fall from its clamp.
Then using a pair of needle nose pliers squeeze the clips that hold the pipes to fuel filter and pull off firmly. You will need a tray to catch any fuel that escapes.
Take the new fuel filter, and offer it up to the vehicle with the flow pointing towards the front of the vehicle. Remove the plastic clips off the old filter and apply to the new filter. Remove the rubber sleeve from the old filter and replace on the new filter. This should be positioned where the filter clamp will clamp around.
Push the hoses back onto the plastic clips ensuring they are clipped in firmly.
Locate the filter back in its clamp and do the nut back up tightly. Check the fuel filter is not loose and mop up any spills with paper towel.
Finally start the car back up, it will take a few turns for the fuel to get around the system again, but should start after about 10 seconds.
