What is the Fuel Meter Assembly?
When you go to the gas station to fuel up, you normally do so because your fuel gauge or fuel meter indicates that you are low on fuel. The fuel meter is the gauge on your instrument cluster that displays your fuel tank level.
On older vehicles, the gauge may have been in a separate pod, though many are integral in the instrument cluster. The fuel level sensor in the fuel tank reads the resistance from the float level, and conveys that resistance to the fuel gauge.
On newer vehicles, the information goes through a body control module, which then directs a signal to the fuel meter. The needle on the fuel gauge goes up or down based on the resistance sent by the fuel level sensor. If the fuel meter assembly is not functioning as planned, the needle may get stuck in either the full or empty position, or the level may read erratically.
Bear in mind:
The fuel meter is the part of your instrument cluster that displays the fuel level.
Any work carried out on the fuel system should be done by an experienced professional.
How to Fix:
The vehicle’s battery is disconnected and rear seat is removed for fuel pump access
The faulty fuel meter assembly is removed from fuel pump assembly
The new fuel meter is fixed onto the existing pump and pump is reinstalled
The seat is reinstalled and the battery is reconnected
The repair is confirmed and the fuel meter tested for proper operation
The fuel meter assembly is not part of any upkeep service, nor does it need adjustment. If the fuel meter does not display the correct fuel level, it may need to be changed. On some vehicles, that means the instrument cluster as a whole needs to be changed. Have one of your expert mechanics analyze the problem accurately and change the fuel meter assembly if necessary.
Common signs indicate you may need to change the Fuel Meter Assembly:
Fuel gauge reads full all the time
Fuel gauge stays at empty even with a full tank
Fuel meter reads intermittently or inaccurately
Importance of this service:
The fuel meter assembly is not a mandatory component for safe vehicle operation, though you may be left in a painful situation if you run out of fuel unexpectedly. If the fuel meter assembly has been analyzed as faulty, have it changed.
