However, IHC switched to Stewart Warner gauges on the next newer series of tractors. In conjunction with this change, IHC also changed the replacement gauges for earlier series tractors to Stewart Warner even though the resistance for the fuel gauge is different. Therefore, tractor owners had to replace their fuel senders when they replaced their original Rochester fuel gauges. The manufacturer name is located around the circumference of the face plate.
