Alan,

The tubing ID is perhaps around 2 mm then? And the OD of the clunk 
attachmernt is about 4 -4.5mm? 

I would inspect the clunk to tubing contact point if I were you. The sili 
tubing will fatigue prematurely when stretched to it's limit like you have in 
your set-up. Sili rubber is no different than any other rubber when stretched 
out.

To alleviate the problem you may try drilling the clunk with 1/8" drill and 
soldering a short piece of brass tubing, next time you inspect the tank
