I smelled gas during the last couple of rides. Turned out the auto fuel valve was leaking. This unit sits in front of the gas tank cap. I checked the fuel lines and am sure the leak does not come from the fuel lines. Questions: What is the function of this Auto Fuel Valve? and is it easy to replaced? If I order the new valve, can I just pop out the old one and put in the new one? I do not want to leave the bike at the dealer and have to arrange rides to drop off and pick up bike. My bike is a 2000 1500SE. Thanks for your advise/comments.
