Fuel tank inspection

[aburke120]

I bought a 90, 19ft seanymph project, and was told the fuel tank was empty. Not wanting to remove the 24gallon tank, how can I know that it's empty. Do these tanks have baffles in them? Also there's a hose on the bow end of the tank, is this a vent? don't know where it goes. There was a soft spot in the floor, and looking at the floor I found that there was a piece down the middle of the floor with screws holding it down, I took all the screws out, the piece of wood and the carpeting came up, and there's the gas tank, the rest of the floor is still screwed down, and the soft spot was in this piece that I removed.

you pull the fuel sender and you look

that's easy enough, thanks

and if you want to siphon the last bit out with a hand pump, you do it thru the sender hole as well.

That tank should be vented thru the hull to the outside.
