I would get the pump and sender unit installed properly. Sounds like the float is stuck due to an incorrect installation.

Fuel gauge is inaccurate. Just keep filling tank till it takes no more. And knowing the gas mileage you get on the car and fuel tank capacity, set the odometer and when you calculate that you are getting close to the bottom, get some gas.

Hi Josh:
I'd start by completely filling the fuel tank.
Since you know how far you usually can go on a full tank, when you have gone about alf that distance, the gauge should show about half a tank, and when you've gone just over 3/4 of that distance, the gauge should be starting to show on the low side.
At least, if you know that the gauge is not reading correctly, you won't run out of gas if you keep track of the distance and always fill the tank completely.
Hope this helps.

fuel gauge sensor in the fuel tank is faulty.
replace that.

If the trouble with the gauge started after you worked on it then you likely damaged or created a restriction to the movement of the sending unit. You will have to remove the tank and double-check your work.

Its very simple. If the gauge is showing half full then fill the tank and see how much fuel it takes. If the amount you add is approximately 50 percent of the fuel tank capacity then you know the fuel gauge is accurate . In that case the computer is giving an inaccurate reading and should be ignored. All you need is an accurate fuel gauge - it does not matter a row of beans what the computer says if the fuel gauge is reading correctly.

Hello. You may have a problem with the fuel sending mechanism in your gas tank or you may have a fungus in your gas tank which is causing it to show much more fuel than you actually have. Drive to an AAMCO repair shop where they will scan your car's computer for free [some auto parts stores now offer this free as well so call around]. If it is mechanical it should show up on the scan, if not you probably have the gas fungus. Some auto parts stores and dealerships now sell an expensive gas tank additive that will kill that fungus.

sounds like you got the float stuck when you installed the new part, have seen this hapeen often

to coorrect this u will need to pull the gas tank and replace the fuel gage sending unit inside the gas tank, hwerwe is the part number for the fuel module which has the seding unit in it.
