The sending unit is located on top of your boat's fuel vehicle.
A sending unit is an imperative department of your boat's fuel operation, as it is bonded for telling the fuel gauge what consistent it should indicate. Some senders custom a mechanical Slogan that floats in the fuel, either in a tube or attached to an arm, and other types peruse the electrical resistence of the remaining fuel to packages the exact to the gauge. Most boats bear a convenient access panel to receive to the sending unit without Stirring the fuel receptacle; otherwise you Testament occasion to disconnect the container and maneuver it to a bounteous accessible business sphere.
Instructions
Securely fasten the wire to the ground connection, replace the access panel, and reconnect the negative battery cable. Remove the old sending unit by disconnecting the wires and removing the five screws that hold it in place. Scrape off any excess rubber stuck to the outside of the tank.
2. Align a new gasket over the five hole pattern of the tank, and slide the new sending unit in place. Screw it in place with the five screws left over from the old sending unit.
3. Cut two lengths of insulated copper wire, and strip the insulation about a centimeter from each end. One wire should be long enough to reach the fuel gauge, and the other should be long enough to reach the nearest chassis ground. Twist the exposed strands together to make a good connection.
4. Bend the ends of the wires in a hook shape, and loop them under the connecting screws on top of the sending unit. Run the wire that is attached to the post labeled "ignition" to the ignition switch, and use silver core solder to solder the wire to the switch. Once it has cooled, insulate the connection with spray-on electrical insulation.
5. Connect the other wire to the nearest chassis ground connection. This connection will likely have the same connection type as the connection to the sending unit, held in place with a tightening screw.1. Disconnect the adverse battery cable, and conduct the access panel above the sending unit. It is usually held in place with a pair of screws or small bolts.
