The fuel guage on most vehicles moves based on a positive or negative ohm signal from the Fuel Sending Unit on the fuel pump assembly. The guage HAS to correspond with the sending unit, or else the guage will read backwards (ie: reading a full tank of gas when your actually on fumes)

What causes fuel gauge to rise and fall upon acceleration?
The fuel sloshes back & forth as you accelerate.
What is the purpose of a baffle in the fuel tank?
It is to prevent the fuel from sloshing back and forth. Fuel sloshing can cause the fuel gauge to be erratic.It is to prevent the fuel from sloshing back and forth. Fuel sloshing can cause the fuel gauge to be erratic.
What would cause your fuel gauge to jump back and forth?
you tell me then we will both know.
Fuel gauge moves back and forth?
It usually means that there is something wrong with the fuel gauge itself. It's like when the speedometer is out, just get i checked by the car manufacturer
How do you replace a fuel gauge sensor in a 1993 Saturn?
the fuel guage in my 1993 Saturn goes wiggling back and forth. how do i fix this problem?
Why are there no gas gauges in Nascar race cars?
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.
What would cause 2004 Malibu fuel gauge to jump back and forth between empty and full?
a bad sending unit in the gas tank.
Why does my Fuel gauge works erratically on 2002 Ford Taurus?
The fuel sending unit is sticking, or the wiring to the gauge is loose. These are the two most common causes of an erratic gauge.
Why does the fuel gauge jump from full to empty and back?
Your fuel sending unit is not giving the correct reading to your gauge
If the Fuel gauge is not working after fitting new fuel pump what could the causes be?
a bad ground
Could the fuel gauge have a blown fuse?
Most vehicles have one fuse that protects all the gauges so if the fuel gauge is the only one not working, the fuse is probably okay. Most causes for a inop fuel gauge is a faulty fuel gauge sending unit in the fuel tank.
What makes the fuel gauge arrow float back and forth giving inaccurate readings of the gas tank?
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!
