'89 23' CC fuel tank condition

[ocuyler]

I finally got to start the long awaited rework of my 23. After removing the console and the fuel cell hatch, I found the entire 8' long panel to be rotted as the glass work on the bottom wasn't finished well and let water in as the caulk failed. Fortunately, everything else looks great.

My consern is with the fuel cell. I can't believe it's 8' long! Is there a way to test it or any thoughts on the wisdom of replacing it or removing it to see what's up down there? What about the foam? Should I repack it when the new panals go back on?

She gets fresh paint and all new hardware. I'd hate to have to go back in there.

Thanks in advance.
