Re: Gas Tank Modification/Solution
These tanks are manufactured to specific tolerances and the plastic is a special compound. It is actually a powder poured into a mold which is then heated and rotated in all directions to evenly deposit plastic. Other older ones are blow-molded. At any rate, any modification to a plastic tank is liable to create a danger.
These tanks come in all sizes. Find one with the length, width, and height that suits your space. Buy one specifically designed for permanent mounting below deck, and use a fill fitting, fill hose, and vent, because filling inside the boat through the tank filler opening is very dangerous. Temporary tanks are meant to be filled outside the boat ON THE GROUND --not in the car, to avoid static build-up.
The extra money spent will be more than payed for by the extra safety.
Gasoline is so pervasive in our society that we tend to become a little carefree and lax about its handling. But, Understand that a tank of gas has more explosive power than dynamite. We need to respect that power and potential.
