Take out the screws and pull it up. If your lucky there will be enough slack in the fuel line to do that and the clamps will fit through the hole. If not be prepared to stand on your head and tear the boat half apart to get to it. Might think about putting in new coast guard approved fuel fill hose while your at it, 10 years is about long enough for that hose to last and it might not be approved for alcohol use.
Thanks Chief
