Craig, yes that is like mine but so far in only 1 section. How did you fix it?
Thanks
From memory I loosened a few bolts under the running boards and pulled the piping & re tightened. It helped a little, but I found by cutting out the lubricating altogether the rubber hardened & it self cured.
The service guy at Williams did say that they don’t lubricate the piping for this reason. Maybe I over done it !
