18 Fisherman Fuel Tank Replacement

[Irish Jig]

I have an 18 fisherman and it looks like I may need to replace the fuel tank. Apparently the plastic has stripped out around the fule sender and its leaking. Has anyone done this before? Do I have to remove the console or can I just take out the floor pannel? Does anyone know the cost of a replacement poly tank? Thanks for the help.

Or does anyone know of a different way to fix this?
