Does a boat gas tank need to be vented?

The vent on your gas tank is necessary to prevent a vacuum block which would prevent fuel from being pumped from the tank to your motor. It needs to be open when operating your motor. Even gasoline and diesel have different containers. When you open the vent on an expanded tank, fuel vapors will escape.

Can you repair plastic fuel tank?

You cannot repair a damaged polypropylene gas tank with epoxy or a plastic tank repair kit, because gasoline will quickly dissolve the epoxy and the leak will reappear. Polypropylene is a thermoplastic, which means that you can use heat to melt the plastic and create a permanent repair in the polypropylene gas tank.

What is the best material for a fuel tank?

Tanks must be constructed of 5000 series alloy, specifically 5052, 5083, or 5086 (note that 6061, a common marine aluminum alloy, is conspicuous by its absence from this list). The specified minimum thickness is 0.090 inch; thicker is nearly always better when it comes to fuel tank material.
