ABSTRACT:
A tank vent system includes a turbo-charged internal combustion engine with accompanying fuel tank. The fuel tank is connected by conventional fuel line and fuel pump to supply fuel to the engine while the pressurized, turbo-charged air connection between the turbocharger and the engine is connected through a filter and a first orifice to the top of the fuel tank to supply filtered and pressurized air into the fuel tank as the fuel is pumped out for the engine. A second orifice between the first orifice and the fuel tank is provided to limit the pressure buildup in the fuel tank and relieve the pressure when the internal combustion engine is shut down.
