I have searched and could not find a write up or service manual on how to remove the floor to gain access to gas tank on 2008 Supra launch 22ssv. I have the rear facing seat on the drivers helm and am installing the wake makers new ballast setup and it requires installation of the larger diameter hose. The only way to do that is to remove the floor board to gain access to the tank. Any help would be much appreciated. Thank you.
