The clips holding the float leave a lot to be desired. However, there are extras provided if you need them. The 12 - 24" is not made like the picture shows. You have a bracket extending down from the top of sending unit. Then you decide, using the instructions, where to mount the floating swing arm and float to that bracket. The black mount is not mounted to a plate as shown. You have to mount it to a much longer bracket. You will have to cut this bracket below where you mount the floating arm. Then you will have to cut float arm to proper length. For the floating swing arm, the instructions give you the suggested length for the depth of your tank. Wire connection to floating arm must be mounted on the bottom to work properly. Depending on where you mount the floating arm on the bracket and where you cut the floating swing arm, this will decide where and when the sending unit will read full and empty, so measure correctly and mount bracket higher or leave swing arm longer if you want to leave some type of reserve when your gauge reads empty. The parts are made of light weight aluminum that bend very easily. If you bend the swinging float arm while installing, your reading will be incorrect. If you have a deep tank and your clearance above the mounting hole in the tank can not be installed by going straight down, it would be very easy to bend. My tank was 22 inches deep and only 5-6" below the gunnel, so I had to install at an ankle and try not to bend the arm. It would be nice if iboats offered a one piece sending unit, like the one shown, in a longer depth than 12".
