Hi,remove n/s/r wheel arch liner to access the filter.,modification consists of a longer fuel filter and 3 pipes ,only 1 pipe appears to be required,the other 2 seem identical to the ones they are replacing.If you wish to replace all 3(my local main dealer does not)you have to remove the rear seats lift the carpets and remove bonded in access plate in floor which will probably need renewing.HTH Steve
