If you are referring to the little arrow under the gas symbol, the arrow points to the side of the car that the gas cap is on. Very useful if you drive a lot of different cars!
A common problem with Honda cars is that the fuel gauge is stuck on full. This problem is solved by replacing the gauge cluster.
The fuel gauge is located in cars. It is used to tell how much fuel is left in the tank. When this gets low the tank will need filling up with more fuel.
Most cars have a schrader valve on the fuel rail that you attach a fuel pressure gauge to. Cars that don't require you to tee into the fuel line at one of the soft connections.
In most cars it is as simple as looking at your gas indicator on the dashboard. Usually on the fuel gauge is a small picture of a gas pump. On one side or the other of the picture there will be a small triangle arrow that points to the side that the gas cap is located on.
Nascar cars do not use normal gas gauges due to the fact that when the cars are in corners the centrifical force causes the fuel to slosh around in the fuel cell, Which in turn would cause the gauge to sometimes show that it is empty and sometimes full. That is why they use fuel pressure gauge instead. Which tells the driver how they are doing on fuel via the needle bouncing back and forth.
The small arrow on a vehicle’s fuel gauge is a simple but important feature that many drivers overlook. Located next to the fuel pump icon on the dashboard, this arrow indicates which side of the vehicle the fuel filler cap is on. Its purpose is to eliminate guesswork, helping drivers quickly identify the correct side when pulling into a fuel station. This is especially useful when operating unfamiliar vehicles, rental cars, or fleet units commonly used in industrial environments. For businesses and operators in sectors like construction, mining, transport, or fuel management—such as those served by PETRO Industrial (petroinddotcom) —understanding this feature can enhance operational efficiency. When drivers know exactly where the fuel cap is located, refuelling becomes faster, safer, and more streamlined. This reduces congestion around refuelling points and minimises the risk of accidents or unnecessary vehicle manoeuvring. The arrow’s direction is straightforward: if it points left, the fuel filler is on the left side of the vehicle; if it points right, it’s on the right. While small, this indicator supports better fleet management and smoother refuelling workflows, particularly when paired with on-site fuel storage and dispensing solutions. In short, the fuel gauge arrow is a clever design detail that helps keep refuelling operations efficient and hassle-free.
WHEN THE LOW FUEL LIGHT LIGHTS UP YOU HAVE VERY LOW FUEL. tHE NEEDLE WONT EFFECT ANYTHING IT JUST HELPS YOU KNOW WHERE YOUR LEVEL IS.
Air fuel ratio gauges rely on a sensor that is very much like an O2 sensor used in a car's emmission system. Therefore you would have to have 'bung' drilled and welded into your cars exhaust system to mount the sensor for the air/fuel gauge. After that, run the wiring and mount the gauge like any other aftermarket gauge.
A gauge for measuring fuel in a tank.
Reset a fuel gauge? There is not reset for a fuel gauge.
The fuel gauge will no longer give an accurate reading.
Generally it involves the float or sending unit. If vehicle had a fuel pump installed recently talk to the people who did it and inform them of this!
