Hi, guys:

My rear-mounted fuel tank has a vent hose attached to a nipple on the top driver's-side corner of the tank. The rubber hose is about 2 feet long and is looped three times into a coil and zip-tied to the frame to keep it away from the exhaust.

I don't fill the tank more than 3/4 and it is still pressurizing while parked in the garage and it also vents both air (the garage always smells of gas) and also gasoline liquid.

A friend suggested adding an in-line rollover check valve to prevent the liquid gas from coming out. It would just be added to the vent hose.

Does that sound reasonable? Is there anything I can do about the smell of the vapours?

Thanks for your input.

John
