I grabbed another tank yesterday (poly), if I'm going to remove it for inspection might as well replace it.
Couldn't really make out much on the plate, maybe Florida Tank manufacturer? I'll get a pic later to see for sure. Looks original though, so maybe someone thought it was a great idea to foam it.

Make sure you have 2% growth all around the poly tank because it will grow when it is holding gas (something molecular) and stay the new size.

Finally got 1/4 of a day with no rain ( we'll light), to try and remove the fuel tank. After a few test spots I feel the tank will be in good shape, so I'm thinking it doesn't need to be removed.


There's a green coating on the tank

And in the few spots I dug out it looks pretty good ( new)

The top looks ok. My advise is you pull the tank, clean all the foam off it and get a good look at the bottom. If it is really ok (be honest), just change the way you tie the tank down. Here is a link to one type of install - main thing is keep air flow around the tank - https://www.yachtsurvey.com/fueltank.htm

I'm with Rickk...pull the tank.  And if you plan on keeping the boat, once the tank is pulled have it pressure tested to ensure no leaks.  Remember, your standing on a bomb....no short cutting this job, imo. 

I replaced my tank last year.  Reinstalled using modified pasco method.  Find description here:
