well those are interesting thoughts. so does this mean if i use the stock gauge and the sender is reversed and i were a pessimist would my tank be half full when i think its half empty? back to the point if i go with the 12 volt sender and 6 volt gauge would it matter which side of the gauge i put the reducer on as long as it is inline somewhere . i am thinking it would be ok on the side going to the tank for this is a negative side and i wouldn't have to worry about shorts . am i correct?
