hi john,i had to remove both rear wheel arch liners and the front drivers one,there are 2 connectors behind the front arch where i just cut the pipe with wire cutters and nipped the ends so not to have brake fluid everywhere,one pipe runs from the front above the air tank and then up to a small flexi hose,then theres a small brake pipe runs from the small flexi hose to another one,so that was the drivers side done,the other pipe runs from the front above the air tank up around where the drivers side was connected it then bends and runs along the top to the passenger side where the top of the rear air springs are fastened in,and bends onto a flexi hose connector,then the same again another little brake line from flexi hose to flexi hose.
in short john do like i did after removing the arches,and snip the front lines at the connectors,i worked from the rear to the front,i did all the drivers side first,but i didn,t connect the front till all the pipes were in,as for the passenger side one,you can get your hands on most of it from underneath, above the exaust.if you use a torch and look through the gap where pins and air line to the rear springs are you will see where the pipe runs.i managed to run it the full length starting from the passenger side across to the drivers and then down the front.
i had to cut the old one out in some places,in fear of catching the air line,so once i ran the pipes to the front i then cut them and put the fitting on,as there is plenty of room,if you put your steering on full lock to the right
