I am using the stock location (behind the front seats) the cell will sit higher than the stock tank and the filler hose will be almost horizontal. The option of using a filler cap on the cell directly
Does not work due to its location (you would have to fill from inside the cockpit not very convenient during an enduro). I have seen MX5 in Koni with the fillers in the trunk (dry break), but I don’t know if that would be legal?
