Hi Mark, I would agree with you regarding the inflexibility of the system hence the reason for mounting it all onto an 18mm bit of ply
. The way I see it is that with the ply being so substantial, there will be no localised movement of ANY part of the system.....The hope is that the ply will have some natural vibration resistance....
I HAD toyed with the idea of using some hose but my main aim was to try and reduce the amount of joints (failure points) as far as possible.
Yeah, running check valves on both pumps. Thought it was a sensible precaution for the money
