They are odor-proof of course seawater resistant and UV resistant.
Pontoon boat gas tank ideas. Portable ones anyway a trend which is apparent by the reduced size of the gas containers perched on the transom of about every pontoon in the fleet. Many builders place the fuel tank in the boat and then seal the cockpit on top of it without leaving a way to inspect or replace the tank. Fresh water waste water or diesel fuel tanks on your boat or RV.
Many pontoon boat owners will carry additional fuel onboard in spare portable tanks. A corollary to this callous disregard by some boat builders is that they install the aluminum fuel tanks in ways that almost insure that there will be problems. I disassembled the capnozzle unit and using dimensions off the nozzle base lathe turned a 34 thick Nylon unit that the Neoprene U shaped gasket fit over.
Leave the gas tank open to allow excess moisture to evaporate. Where you used to see a brace of gleaming-orange six-gallon metal cans or a pair of cherry-red plastic container capable of holding eight gallons or more of gas now you see matched pairs of Mini-Me versions of the portable fuel tanks. Of course that would put the weight of the motor fuel and battery all at the very back.
Filling directly from a gas can usually had gas running all down my arms when filling while boat was on trailer or into the lake when filling while boat is tied to the dock. This device is made from marine grade UV-resistant vinyl and has an integrated rubber football style valve. If your pontoon boat does have dual tanks then simply replace one or both of them with bigger tanks.
Ethanol absorbs water but it has to have water to absorb first. It is the full responsibility of the end user to determine if these products are suitable for their application in their respective area. This is a good idea as some activities such as water skiing and tubing can use up a lot more fuel than you expect and some pontoon boats come fitted with a very ill-equipped fuel tank that simply cannot hold enough gas.
Once you feel like its as dry as it can possibly get you can then add in some fuel tank cleaner. Many pontoon boat owners will keep one 6 gallon tank as an emergency reserve and put on another 12 20 gallon tank like this one and use it as the main fuel source. OK I hatched the idea of using a 1 gallon plastic gas can that I had been using for my chainsaw but modify the gas cap for marine use and the quick connect coupling to the fuel line.
