Changing the gas tank - 1999 Nissan Maxima

Your sending unit is inaccurate and needs to be replaced.

you will have to drop the tank to gain access to the tank unit seal to change. while there check other seals like the vent sensor.

Should not have caused significant damage. Change the oil and check again after a few days.

should have flap door where you put gas nozzle into filler tube to fill up gas tank.if flap door not missing not too much got in gas tank.add more gas and gas treatment to remove water if you have stalling problems drain fuel tank.change fuel filter.

most fords i have had have this problem the small vent hose gets a hole in it and gas won't go down, need new filler tube. u will have to lower gas tank and remove screws from filler neck around cap to change out , easier if tank is empty.

This problem is caused by a defective gas gauge sending unit inside the gas tank, to change the sending unit requires that the gas tank be removed from the car to access the gas gauge sending unit.

If the gauge works on the rear tank but not the front, the problem is most likely the sending unit in the front tank. You will have to drop the tank to change it. I guess what I would do is, set your trip meter to zero when you fill the front tank. Then, run that tank to the point where the truck is starting to run out of gas and then switch to rear tank. Keep track of how far you can go on the front tank. Then when you refill the front tank reset the trip meter and switch tanks about 20 miles before you think it's going to run out. It's not a good idea to run those pumps dry. Just make sure you have gas in the rear tank. If you do decide to change the sending unit, run that front tank as empty as you can, also, I would change the pump too. In 92, I think the pump or the sending unit can be replaced seperately. The worst thing about changing those in tank fuel pumps is getting the gas out of the tank. No trip meter? Just write down the mileage from the odometer. Good luck.

this is not the gas gauge, this problem is caused by the gas gauge sending unit inside the gas tank, drop the gas tank and rep[lace the fuel pump/sending unit module, about $200 for the part from rockauto.com.

disconnect the battery, put a piece of plywood on a jack and place under gas tank, remove the straps, lower the tank, remove fuel pump, change tank
