Gas guage said 1/4 tank pump kept shutting off like it was full
I could only put a little gas at a time in the tank and the pump would shut off. I finally got it to about 3/4 of a tank and couldn't put any more in it. I'm not sure if I have a faulty gas guage or something wrong elsewhere.

I have the dealer that sold me the vehicle checking the rear end, the sensor that needs to be replaced, and the gas fill problem. I will get back to you after I hear back from them. I took my car to them yesterday morning, so haven't heard yet.
Thank you for writing, I'll let you know. Judy

Gas as in gasoline or gas as in LPG gas? If its petrol, the fuel sender may be out of adjustment. (Usually means a new sender) If its LPG, the fuel stations are set to automatically shut off at 80% full. The gas tank will never actually be full to the brim but the gauge should be showing full if the gas nozzle keeps shutting off. Have a look on the LPG tank itself, they have a little gauge on them which shows how full it is. I have 2 tanks on my car , when "full" or when the pump shuts down, the tank gauges show just under full but the gauge on the cars dash shows full (2005 BA Ford)
If the vent solenoid where stuck than the pump would constantly shut off on you. It would literally take you 30 minutes to fill you tank.
When everything is working correctly the pump will shut off and that is all the gas you should add to your tank. Adding a little more gas is fine but anytime you overfill the tank you run the risk of ruining the charcoal canister.
On your particular vehicle it is not that expensive. Try in on a honda and your looking at a minimum of $1200 dollars!
If the gauge is reading ful than it is full. There is no need to add more.
So do you know if you have gas in your tank or not? You need to check for fuel pressure to make sure your pump is working. Inside you fuel tank is a fuel pump module which consists of your fuel pump and fuel level sender. It sounds like you are going to need to replace that. Can you hear your fuel pump buzzing. Open you gas filler cap and put your ear next to it while having a helper turn the key to the run position not start position. You should hear it run for about 5-10 seconds and then shut off. If you don't hear it you have a problem with your pump. It can be with the wiring, feul pump relay, or the pump itself. It is usually the pump. But even if you can hear the pump you still need to check your fuel pressure as the pump may be buzzing but not working correctly. Also check your fuel filter.
A loose connection on the sending unit could cause the problem but also moisture in the tank in cold weather could also be a factor in which i would add fuel line antifreeze to a full tank of fuel..........Hope this helps you out.
The gas guage has a sending unit in the tank attached to the pump, there is a small circuit board on it that has smal"fingers" that send the signal to the guage.These get worn off and thus sends a false reading to the gas guage in the dash. The gas tank must be removed and a new unit put in to solve the problem. I had to do this repair to mine. As for the gas issue, just try pulling the nozzle back out of the filler neck when putting gas in, sometimes the overflow tube gets plugged up and won't allow the air to escape as the gas goes in the tank, making the gas pump think the car is full, pulling the nozzle will allow the air to escape. Hope this helps.
The gas guage is a seprate problem, the gas fill hose may have a sharp ben in the hose or kink, the gas pump hase a shut off valve that shuts off the pump if gas does not flow freely ie:blockage or full tank, I would visualy inspect the filler hose from the gas cap to the tank for again sharp bends or kinks, if the filler hose is in anyway restricked the pump may asume the tank is full.
the gas guage: is usualy a simple flot on a rod in the tank (like a toilet tank has) instead of opening or closing a valve it operates a "potentiometer" veriable position sensor (kind of like a dimmer switch).
if the float gets stuck the guage will stay in that position, the guage gets the signal via the wire harnes, so check the electric circit.
A trick I used on one of my jeeps (I removed the guages ) I filled the tank, reset the trip odometer to zero, put a jeerycan and a couple gallons of gas in the jeep, then drove normaly a week or so till I ran out of gas. wrote down the mileage on the trip odometer. gerrycan gas got me to the gas station.
divided the mileage by half. I fill up the tank all the way the reset the trip odometer to zero, when I reach the half mileage of the tank I fill up again and repeat
I found the problem!!! There is a square steel box under a plastic cover under the gas tank. This box is to filter the gas fumes that comes out of the gas tank when filling. Well the hose from the filler neck (or tank) fell off and was hanging there. I put the hose back on (very easy) and that was that, no more problem! I talked to so many people and mechanics and no one knew about this problem. I suffered with this for so long!. So do it yourself and save a ton I'm sure.
