Removing Boat Floor Strong Gas Fumes From Boat - Is This Normal?

Strong Gas fumes from Boat - Is this normal? - removing boat floor

In 2002 I bought a Glastron boat with a 40 gallon tank, three weeks ago. I hold in my garage now, but tomorrow's out of my garage is filled each day with the strong smell of raw fuel. The smell is particularly strong in the area of the factory where my skis. I found a refuge on the floor with screws, I removed and tested in the pipes are closely related to the tank in context. Is it normal to have great smell, and if not, when is a good place to buy parts online?
