The the fuel level sensor in the gas tank needs to be replace, the official name for this part is the gas tank sending unit. Try cleaning the plug connector for this electrical part before buying a new one they are sometimes $100.00 +, I am pretty sure you can gain access to this part by removing the lower section of the seat in the back exposing a access plate remove the plate look for a wire with a plug unplug clean and reattach, if the gauge is still malfunctioning replace the sending unit located in the tank. Some vehicle do not have this access panel so the gas tank must be removed to gain access to it, however if you jack up the back of the car support with jack stands and crawl under the car where the gas tank is you may be able to see a wire leading to the tank look for a plug and unplug spray with electrical cleaner and plug back in, then check for proper fuel gauge operation, if this doesn't help replace the sending unit. If you are going to attempt this job I recomend first before pulling out the back seat purchasing a Haynes repair manual at you local Advance Auto Parts store or any parts store that carry the repair manuals this will guide you through the job and you will save about $200.00 labor cost. PS make sure if you are going to remove the tank it is close to empty they are heavy.

Town and Country Van running out of gas and guage says half a tank what could be the problem?


If your fuel gauge is showing you in accurate readings this is normal to all vehicles that are not used to fill-up gas full regularly but sometimes the cause of the inacuracy is due to faulty float valve in the gas tank you need to replace it

1989 silverado gas gauge shows full even when cluster removed from dash.


The sending unit in the tank provides a ground to the gauge depending on the float level. The gauge can "rest" anywhere if the power and ground circuits are not connected.
You would need to know if the gauge has power and is getting a ground signal from the tank.

Gas gauge was just under 1/4 tank, I filled up and the gauge did not register full. after driving for approx 30mins the gauge slowly moved to full.


There is a small float in your gas tank something like the one in your toilet tank(no I'm not kidding).Its position regulates an electrical current and based on its resistance gives a reading on your gas gauge. My best guess is this float got a bit stuck in the low position and it shock free after some time on the road.This is more common than you would think.Keep an eye on it and if it freezes in empty position or sometimes full position it will need to be replaced. Hope this helps,good luck.

1987 fuel level guage issue 87 F150 Lariat XLT 5.0 2wd. Have a very similar situation. Front tank position shows empty even when I know there is gas. Rear tank position shows full after refilling but...


the gas is regulated from the switching valve you control off the dash. Check the valve to hear it switch
have a friend help you do this. it will be located under the truck between the two tanks. You may have a faultly valve or switch rattling inside changing the tanks setting also while driving which will be hard to tell

Gas gauge is not reading correctly. Shows a full


the problem is caused by a defective gas gauge sending unit, this part is located inside the gas tank, you must remove the gas tank to replace it.

When the gas tank is full the gas gauge shows as empty. When the gas tank is empty the gas gauge shows as full.


Well that tells me that someone installed the wrong fuel level sensor. Your going to have to drop the tank and pull the pump and float assymbly out. Then go to a parts store and get a sending unit that has the opposite resistance of that sending unit. Just wait until the tank is empty so its a lot lighter. You can call the parts store or go down and see if there is multiple sending units. The sending units work by resistance, when the tank is full the float moves up and turns a wheel in the sending unit, which either removes or increases the resistance causing the gauge to lower. The sending units either give full resistance at full or no resistance at full and then changes as the level goes down until it does the opposite at empty.
