These gauges were one of the most frequent warranty claims for new Tiaras in 2004. My dealer said they will replace them once and then you are on your own. We had our dealer install Tank Tenders instead of fussing with the original. It is a very simple design that is bullet proof. Ours are very accurate and work flawlessly after twelve years. We really appreciate knowing when we need to pump the head with no guesswork.
