Every now and then I get a whiff of a gasoline smell from my P1K3.. usually when bouncing a bit or going up hill. Could it be from a gas tank vent line when the gas is swirling around in the tank? There are no gas leaks or any leaks of anything that I can see when parked. Just wondering if I should be concerned about it? Have had this happening pretty much since new from this spring, about 150 miles on it now.
