Sounds like the cable needs tightening on the servo under the tank. Take the side cover of the exup valve and check that this isnt coming loose too.

It sounds like the vibration is coming from the underside ,on the exup valve itself.Is there anything to be aware of when i remove the cover.Will anything spring off and be lost forever?
