Whether or not a march fuel gauge will fit a B13 tank depends on the size of the march gauge. You should be able to find a march gauge that will fit on a B13 tank.
The fuel gauge gets a reading from the fuel level sender in your fuel tank. There is a float attached to a lever floating on the fuel. The lever moves ( as the fuel is depleted or refilled) along a variable resistor in the sending unit. The guage detects the variance in resistance, telling you how much fuel is in the tank.
The fuel sending unit sends a signal to the fuel gauge showing the amount of fuel in the tank. when the fuel gets to a certain point, the sender turns the low fuel light on.
The gas gauge in the Eddie Bauer Explorer probably does not work due to a bad fuel sending unit. The sending unit is in the fuel tank in the same access area as the fuel pump.
my gas gauge doesnt work and i dont get a warning light when about to run out, mine goes to fuel when its about to run out
I am in the process of fixing my fuel gauge problem now. I took the fuel pump out of the tank. at the top of the float arm there is a memory stick much like the sim card you install in your cell phone. it has many copper lines running through it (looks like the gas gauge) and the read needle on your float arm gives the reading of how full the tank is. the needle on the float arm seems to rock back and forth or side to side which over time pulls the needle which is spring loaded (no actual spring, but by the bend in the metal) away from the chart or sim card. you can try very very gently to put the spring back in the needle by inserting a small regular screwdriver or equivalent behind it and try and get the needle to make contact with the sim card again. if successful your fuel gauge should work properly again and you save a couple of hundred bucks.
The fuel tank pressure sensor is for the EVAP system. It has nothing to do with the fuel gauge sending unit.
check for a damaged fuel tank
Bad sending unit in the fuel tank.
signal from the sensor inside the tank to the gauge
THE FUEL PUMP FLOAT HAS GONE BAD OR THE GAUGE NEEDS TO BE CHECKED
A faulty fuel gauge sending unit located inside the fuel tank would be the most common reason
if you put gas in the tank the gauge don't work what is the problem Probably the sending unit in fuel tank is corroded. Either replace unit wit a new fuel pump or try pulling pump out and cleaning crud from float unit and sending unit and the contacts. Fuel pump is in fuel tank
Most likely either a bad float in the fuel tank or defective gauge
It sounds like you have a bad fuel sending unit. It is located in the fuel tank and the tank must be removed to replace it.
The float in the fuel tank may need to be replaced.
fuel sending unit located in the tank is probably bad
The gas gauge and fuel pump are on two separate circuits tand both go inside the gas tank. The gas gauge usesf a float that moves a resistor according to fuel level. Gas gauges. When you experiewnce the gas gauge not working at all I would look for a disconection external to the tank first. If you cna send six volts from the tank sender to the gauge this should cause the gauge to read. If it does then you know the problem is with the sending unit and it must be removed from the tank to repair or replace.
