This is my simple method. Threaded a section of rubber tubing up the pipe and placed it in a strategic place and relying on the jointing piece further down to absorb vibration. It's also got a cable tie around it somewhere but can't remember off hand where or what to
. It's been like that for over 7 years and, so far, it's been ok. I don't know what BSA would have done under the tank - maybe nothing. It would be interesting to know.
I could have told you in mid 60s - but it's a bit late now. Anybody know?
Rog.
