This was taken this evening, i have answered my own questions after some inspection in the daylight, but thought id let you all know the findings as i think they are shocking (hoping mine is a one off)
The piece out lined in blue is the area that is photographed. it has been rubbing the pipe so badly its worn completly through! I think it would be worth people using the 1st 4 pictures to locate this area and see if your pipe too is rubbing.
i have cut the pipe to the left of the rubbed area so i could photograph it for you all, and my solution is this:
remove battery and battery tray, follow the pipe back to beneath this area. disconnect it from its rubber connection.
cut it where i have.
get some high quality 12mm internal diameter piping (il be using some sourced from a hydrolics specialist next door to my dads work) and clamp it either side of the cut.
then il ensure its well away from ever rubbing again!
hope this may help some one whos pipe is also rubbing and they do not know.
