Fuel tank

[Islandtrader]

There is a big chunk of foam both fore and aft of the tank. i.e., under the leaning post and before the casting platform.
Is there any reason to leave that foam in there?
Or should I pull it out and get rid off the old wet, heavy foam, which would maybe allow me to through-bolt the new leaning post.
Also, would drilling a few holes in the pan that holds the fuel tank be ok?
I'm thinking that would allow water to drain away instead of sitting around the tank

I think it has been said many time before...get rid of the old wet foam.

Place the tank on 1/4 inch runners and place some limber holes in the coffin.
