Okay JoshOnt, if you are wanting one sender unit to swap out between the three gas tanks, I think you will not find anything on the market for that option. However, if you install a fuel level sensor in each tank then that would work with some type easy swapped between connector to the fuel gauge. And if you want a very good sensor/sender, you can buy the quality reed design ones. But they are pricey. Or you could buy the lesser quality type with the swing arms designs and install one in each tank for a lot less. Problem I see is the swing arm types can get stuck with swapping out tanks. If you can make certain the swing arms are free to move when you swap the tanks out, then go for it... JMHO!
