I agree its the sending unit also in the gas tank.
I would get the price for the part and possibly for the fuel pump also. You may be able to do these seperately but since the tank is out and based on how many miles are on the pump in the tank you may want to think about doing them both.
Now the only con on doing the pump is there are alot of junk replacement pumps out there and i have seen them go out in less than a couple months,, and this prabably would be the pump you get when the pump really goes out. So it your call on whether or not you replace the pump. Also when replacing pump or just sending unit you should replace the harness also. Poor connections can lead to future fuel pump failures

The sending unit in the tank is more than likely faulty. These are bad about going out causing this problem. The cost of this repair generaly cost about 800.00 dollars.

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

CAR switches itself off when fuel is on querter tank


check the calibration of the sender unit as may actually be on empty. Find out the exact capacity of the tank and add a known amount of fuel and see where the gauge reads. For example if the tank is 60 ltrs or 20 gallons add 5 gallons and see where the gauge reads. 5 gallons in 20 gallons should read 1/4 or in your case after the engine stops should read 1/4 full. If it reads 1/2 then the sender is out.

Why is gas gauge not working correctly since fuelpump was replaced.


Is this a flex fuel vehicle. If so, call the dealership and ask the parts dept. if there is a gauge module (perhaps behind the instrument cluster). This may be the culprit and needs to be replaced.

I have a 2005 Mercury Sable that suppose to have a 18 gallon gas talk, but I can only get at most, 13 gallons of gas in it and it never will fill up. I have never been able to fill the gas tank up in full,...


With the gas gauge not working right, you have probably never let it get completely empty. And as far as the gas gauge goes, it's probably the fuel level switch. you can not purchase these separate from the sending unit. It would be a $500.00 + I would live with it untill the pump goes out, because this is part of the sending unit also.

On my last fill up i pumped 33 gallons, when previous fill ups were less than 26 gallons. I have a 1999 expedition Eddie Bauer. I thought I had a 26gal tank, since with the warning light on and saying 10...


The 99 expedition comes with a 26 gal tank as standard equip. and there is an optional 30 gal available. I suspect the gas pump you used is not accurate, and needs to be recalibrated. I think it's just a coincidence that the gauge is acting up now. Hopefully I'm wrong, and by some miracle you actually are now getting 300 miles on a half tank of gas! You may have a bad sending unit, this would result in inaccurate fuel tank readings.

Why can i only fit 13 gallons in my 19 gallon gas tank on my 2002 jeep wrangler sport 4.0


You can usually only get about 18 gallons in a 19 gallon tank and you likely have 4 gallons left in it when the gauge reads empty
