Most sensors have a mechanical floating arm and a rheostat. When the arm is all the way down, in the “empty” position, the resistance in the circuit to the gauge is near zero. As the arm rises, resistance in the circuit also rises to around 200 Ohms. This resistance is what moves the needle on the gauge.... see more ›
There is nothing to fix inside the fuel gauge; it's sealed and not serviceable. If your gauge is good, check the ground at the sender with your multimeter set to ohms. Look for a “no resistance” reading between the ground on the sender and your boat's battery ground. If your ground is bad, fix it.... see more ›

Fuel gauges work by measuring the voltage across a variable resistor within the sensing system, to determine the level of fuel; which is then relayed to the driver via the indicating system.... see details ›
A fuel gauge that only reads full may be caused by a faulty fuel gauge resistor sending the full voltage to the fuel gauge at all times. The fuel sending unit is constantly in motion when a vehicle regularly uses fuel, which causes constant movement of the wiper in the variable resistor.... view details ›
The gas gauge in the instrument cluster is the visual indication of activity in the fuel tank and sending unit. Some gas gauges are directly controlled by voltage feedback from the sending unit, while others are controlled by the instrument cluster, which itself gets voltage information from the sending unit.... see details ›

The Measurement Is Very Accurate
While a float-type gas sender unit can record changes in the gas level, the rheostat resistance measure is not as sensitive as a capacitive liquid level sensor.... read more ›
The two major problems that gauges usually have is that they are either inoperative or they read incorrectly. Reading incorrectly can be more dangerous, as the gauge appears at first glance to be working. If the gauge is inoperative, disconnect the sender terminal and turn the ignition on.... read more ›
- Turn the ignition of the car on and off several times, and then check if the fuel gauge needle moves. ...
- Test the fuel tank's sending unit grounding wire.
- Disconnect the wiring of the sending unit of the gauge and check the fuel gauge.
The most common reason a fuel gauge is not working or is inaccurate is due to a bad fuel level sending unit. It can also be caused by bad wirings between the gauge and fuel sender or a blown fuse to the fuel gauge. The fuel gauge itself can also be damaged.... see details ›

How does a fuel sender work? Fuel senders have a rheostat that provides a resistance to ground. As the fuel arm moves from the empty to the full position a contact is moved across the board on the rheostat which varies the resistance seen by the fuel gauge. For example a 69 Camaro has a 0-90 ohm fuel sender.... see details ›
