WATER LEVEL SENSOR, 79-92
Water Level Sensor, 79-92
Does not include Seal**Note: The 89-92 Sensors are outrageously expensive. The only difference between the 79-88 and the 89-92 is the electrical connector. If the connector is simply changed over (it’s just male/female bullet), then the much less expensive 79-88 one works fine.
