Re: OMC remote gas can cap question

Fact is, there is NO vent in the cap. The vent is in the fuel fitting on top of the tank. You’ll see two pins sticking out of the fitting. One is a fuel valve, allowing fuel to exit the tank into your fuel hose. Other is an air vent that allows air into the tank as fuel leaves. There’s a check valve that prevents air from escaping the tank. It is normal for them to pressurize a bit in the sun, warm day, etc. If all your hoses, fittings and carb bits are in good shape, it isn’t an issue. If you’re worried about pressure forcing fuel through the carb or whatnot, unplug the tank when not in use.
I prefer these tanks as they tend to allow less moisture into them, resulting in fewer water in the fuel problems. It is fairly easy and inexpensive to rebuild the fitting if needed.
