Your fuel gauge is connected to a fuel sending unit.
This is particularly critical when working with a fuel method.2. Expansive the access panel above the sending unit. If your vehicle does not have an access panel, you will need to remove the brackets that secure the fuel tank and disconnect the filler neck, then pull the fuel tank out enough so you can reach the sending unit on top of the tank.
1. Disconnect the detrimental battery cable so that there Testament be no unwitting Glimmer when creation electrical connections.Fuel receptacle sending units are tube-like devices that mail a word to your vehicle's fuel gauge telling it what to bravura. Some older senders employ mechanical floats to scan the fuel akin, either along a track or on a cantilever arm, and some models convenience a sender that reads electrical resistence of the remaining fuel. Sending units besides come with two contrastive wiring configurations, two-wire and three-wire, which must match up to the symbol of posts on the back of the fuel gauge for it to operate licence.
3. Determine how many posts your sending unit has. The number of posts on the sender should match the number of posts on the back of the fuel gauge, either two or three. Cut the appropriate number of wires, two should be long enough to reach the back of the fuel gauge if it is a three-wire sender, and the third long enough to reach the nearest chassis ground connection. If it is a two-wire sender, only one needs to reach the gauge.
4. Strip 1/2-inch of insulation from the ends of each wire, and twist the copper strands. Slide the ends of each wire into a ring connector, and connect two wires to the positive and ground posts of the sender, securing each of them with a washer and locking nut.
5. Slide the ring connector of the wire connected to the positive post of the sender to the post labeled "sndr" on the back of the fuel gauge. Secure it in place with a washer and locking nut.
6. Slide the ring connector of the negative wire around the connecting post on the nearest chassis ground connection. This will be a part of the metal frame that has not been painted. Secure the connector with a washer and locking nut.
7. Reconnect the negative battery cable and turn on the ignition to test your sending unit and fuel gauge.
