2002 23'.... Fuel in the Bilge ((facepalm))

[Conundrum]

Ok guys... so my '02 23' all of the sudden has fuel in the bilge. Any known issues to check first? Should I pressure test the tank first? Any suggestions on how to do that? I don't want to give the tank a leak it doesn't have by putting it under too much pressure. I'm thinking (hoping) it might be the fill or vent hose as it seems tied to when I fill up, although I'm not sure how on earth if that's what it is to manage to replace those hoses...

I love this boat but this has me worried....

Thanks in advance
C.
