Teleflex Morse Fuel Sending Unit Instructions

The Teleflex Morse is a marine fuel sending unit manufactured by Teleflex, which is a company that makes and distributes marine gauges and electrical supplies. The Teleflex Morse fuel sending unit is used for inboard boat motors. A sensor on the unit is affixed to the boat's fuel tanks and monitors the fuel level inside the tank. The sending unit transmits that information to the gas gauge, which in turn lets the driver of the boat know how much fuel is in the gas tank.
