Steve Grimsley did an excellent article yrs ago on replacing the old cork float on these manual gauges. I followed his instructions almost to the letter when one of mine sunk and had to be replaced. It has continued work well ever since. That has been at least 20 yrs ago.

A better solution is available these days rather than that method... Use the now-available “Nitriile” floats that sell for less than $4.
