SOURCE: wrong reading on fuel gauge

Normally this problem is due to a bad sending unit. The sending unit is the actual device which transmits the level of fuel in the tank to your fuel gauge. The most common cause is a stuck float. The device works by means of a flotation device, often made of a petroleum resistant plastic encasing a foam or cork "float, " which is attached to a light weight metal arm. The arm moves as the float raises and lowers with the level of fuel. This arm connects to a switch which increases and decreases resistance in the circuit. If the arm is stuck or if the float is allowing fuel in it you will get an inaccurate reading. A "logged" float (one filled with fuel) usually reads below the level, whereas an arm which is sticking will read above the level. Now, if the gauge has been reading this way since the car was brand new, the other likely cause is that the needle may have been improperly placed on the gauge at the factory, or the windings in the gauge may be under or over wound causing the inaccurate reading. If you are mechanically inclined you may be able to replace the sending unit yourself. Keep in mind this can be a dangerous procedure for a first time mechanic as it may involve removing the fuel tank from the vehicle. Some vehicles offer access to the upper portion of the fuel tank via an opening located in the trunk under the trunk mat/carpet or under the back seat. If this is the case removal of the fuel tank is not normally necessary, but you will still be working with the fuel tank. If you are able to do this procedure in the vehicle, keep in mind you will first want to disconnect power to the fuel pump and sending unit. You can disconnect the negative battery cable, but I believe on an the kadette you will need to obtain a special cable from your local auto part supply to maintain power to the ECU or PCM to prevent damage to the computer or loss of programming. At the very least remove the fuel pump relay and disconnect any fuse/relay related to the dash gauges prior to beginning this operation. Also be sure to remove the fuse for any possible ignition source inside your vehicle, such as dome and courtesy lights. Keep cell phones away from the work area as well. If you use a "trouble light" be sure it is marked as safe for use near fuel fumes. Keep doors or windows of the vehicle open to allow vapors to escape so you don't suffer any ill effects and to further reduce ignition hazards. If you must remove the fuel tank, practice good safety. Do not be under the tank at any time. Be sure to remove it with very little fuel in it. Go slowly and be sure you don't break any wires or lines. It is a very involved process and may be best left to a certified mechanic or at least one who is very experienced. Keep me posted and let me know if this helps!

SOURCE: Fuel leaks from rear tank to front.

The leaking from one tank to another was covered by a recall from Ford. Not sure if they still foot the bill for installation of the required check valves. These are still available from the dealership. The rear one is the hardest to install. The check valve can be installed without pulling the rear tank. As for your front sender I would clean all of the connections to the sender and make sure it has a decent ground. If it still only reads at the 1/4 tank level you will have to replace the sender to rectify the problem.

SOURCE: 2002 Chevy Suburban: Fuel gauge reads empty, tank is half full

Youre gauge is controlled by a plunger in the fuel tank which is attached to the sensor and the fuel gauge. it sounds like when the plunger goes down half way its either getting stuck down lower then it should. Needs replacing. Any mechanic can do this install for you.

Fuel gauge is not reading properly 2006 Mercury Mountaineer


Fuel gauges are not meant to be precision instruments. You might want to fill up a 2 gallon can and drive the car until it runs out of fuel to see how low the gauge will go before it's really empty. Use the 2 gallons to get back to a filling station.
I once spent three working days trying to get a 1972 Chrysler to read full when it's full, half when it's half and quarter tank when the tank has a quarter amount of fuel. The customer did not want to accept anything else, but in the end all I did was to get close, not exact.
It is possible that the fuel float in the gas tank is "drowned", that is, the plastic float might have a slow leak and some fuel found its way inside. This will cause the float to submerge slightly and give you a low reading. To check this you will have to remove the float unit from the tank.
In any case, if you feel up the job (not easy) remove the float unit from the tank and manually move it up and down while checking the meter reading. You can bend the wire holding the float to correct misreadings.
Personally, I wouldn't bother, just be aware that when the reading is low, feel safe that you still have enough fuel to get to the next filling station.

Fuel gage aint working


all parts may be new but if the fuel gauge sender float has been bent when being installed into tank this will give false readings - if the float has been bent up during installation then it is likely that it will only read fro three quarters of a tank up as the float can not get any lower due to being bent, I recommend that a new pump/float is installed very carefully.

The fuel guage reads three quarters full when its around a quarter full..sometimes half full..its just erratic


Sounds as if the float has seperated from the sending unit. It will need to be pulled from the tank to be checked and/or repaired.
