This is a simple job! a bit awkward with out a pit!
New filter is about £7 - gsf!
Jack the rear drivers side up and put axcels stands on the bar going across (not sure what this is called)

then remvoe the jack
unscrew either side of the filter (i had to soak mine in wd 40 overnight) , each side has different size bolts! use 2 spanners either side one on the bolt and one on the filter pushing against each other so you don't move the filter around to much, HAVE A BUCKET READY TO CATCH THE FUEL! there is not much about half a pint maybe a little more!
Undo the bracket holding the filter and remove, fitting is reverasal of removing! it does state to renwe the metal or rings on each side, but i did not bother, as i did not have time to get them!
hope that helps
