Michelle,
You were spot-on! I did step back and trace the filler hose.
A few panels that were removable brought me to the findings of a starboard side slow leak in the tank.
A replacement tank was still available from the company that built them years ago in Seattle.!
I found a company here that would tackle the job. While I am mechanically inclined, I did not have the time to
replace it myself. It will be competed in late September by an excellent vendor.
No Tolly this season! Huge letdown for the fam and the frineds who enjoy her with us every summer....
Thank you for the response... cheers.
