Is there really a difference between the two and how do I know which one I have? Seems my gas gauge likes to die after going down to 1/8 tank but works above it so I assume the sender is going bad. Does 1/16" really make a difference if a rubber tube is used to connect the fuel line? If I happen to get the wrong size, could I still use it or do I have to make sure I get the correct size the first time?
