Should be done as so
-=-=-=- DO THIS WHEN THE CAR IS COLD AND HAS NOT BEEN MOVED FOR AT LEAST 2 HOURS-=-=-=-
# Jack the side of the car up doing the handbrake an chocking shizzle
# With a No.2 cross head unscrew the holding bracket and remove the cover plate (only on eco4 models)
# with either a pair of long nose pliers, circlip removers or AC hose removers unclip the rear clip by pushing each side of the clip in and away from the filter, be careful if the filter is perished the clips will be brittle and snapping them will mean hours of work. once disconnected be ready to catch alot of fuel! if your new filter came with rubber stops on each end use one of these on the old filter to save spillage.
# Repeat the process for the front plugging it
# with the filter now removed the refitting is the reverse of removal make sure the new clips are used and that they clip in place, give the unit a tug if your not sure. screw the bracket and cover if you have one back on then your done.
# Dispose of the filter responsibility and any gloves used for this, also make sure to wash your hands
