33 Powerplay Question
 

I have a 33 Powerplay I/O 1991. I have just pulled the fuel fill hoses out to replace. I want to replace the vent hoses does anyone know if there are deck plates under cockpit flooring to access the vents on fuel tanks (it doesn't feel like there are any) If not does anyone known were the vents are located in tanks. I see the hoses go through the stringer in the area toward the front of the tanks.

If you can see what manufacturer made the tank(florida tanks etc.) you can call them for a print.
