Question about 2002 Kia Optima

Gas Tank Blockage

Something is blocking my gas tank because when I try to put gas in it. It keeps shutting off like it was full. It can only take about 1/10 of a gallon and then I have to wait until it goes done before I can start pumping again. It takes me about 1/2 to fill my tank. What's wrong??

    How hard is it to replace? Could It do it or should I have it done? How much do you think it would cost? Thanks for your help

    My '02 Kia Optima does the same thing! It's worse in the winter than summer - right now it's about -30 degrees and I can only put in a few gallons before I'm too frozen! It's started to pour out of my car as I'm putting it in and I can hear it gurgling down. Nobody wants to touch it but a dealer but I can't afford to go there for $100 at least just to look at it!

    HELP!

I had the exact same problem, turns out, there is a 2 lines going from the gas tank to where you put your gas in, one is for the gas to go in and one is for air to get out. on mine, there was a sliver seal from a bottle of heat that i had poured in during the winter. the seal was the exact size of the return air line and blocked it from air coming out. this forced the air to come out the gas part and splashed around a lot causing the pump to shut off, i bet there is a blockage in the line that goes from your nozzle to your tank. it is easy to take off, but it is very dirty

I have an 03 Optima with the same problem. I removed the vent filter attached to the filler neck, an cleaned it with compressed air. I also replaced the pressure sensor located behind the fuel tank. My problem was solved.

Gas tank will not fill up on 2001 ford expedition


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)

With my 2005 Chrysler Town and Country van, I have trouble fueling the vehicle. The nozzle keeps shutting off as if the gas tank is full. What do I need to do?


Usually a sign of a blockage in the vent pipe inside the filler tube, or the vent for the gas tank. Air pressure inside the tank has to be equalized as the fuel is added.

Gas pump shuts off like its full many times while trying to refuel.


Usually a blockage in the filler tube or a vent problem.
You may have to take the filler tube off and inspect it. There should be a tube inside or outside the pipe to allow air pressure in the tank to equalize.

Hard to fill with gas when try to put gas in tank it keeps shutting off the gas hose it acts like i am topping off the gas tank but the tank is far from full


Hi this is a common problem, the problem is to do with the breather hose from the tank getting blocked this is a common fault, but to replace the breater your going to need to get the tank lowered from the car so you can get to the breather hose on top of the tank.

if your doing this yourself then you will need to get a workshop manual to do this as this is quite a lot of work involved.

their is no easy fix its going to be a case of changing parts on the tank

let me know if you need further assistance ok

plz rate this post as i have a whole page of unrated posts, thanks

2000 sonata; difficult to put gas in car. Gas


no its not the vent.it is the restrictor for the nozzle for unleaded gas.(thinner/smaller then leaded) causing a back pressure when you are filling up.sorry but you will just have to fill up slowly like i do....

2003 hyuandi accent - i have trouble putting gas in the gas tank . It will only put in a little at a time as the gas pump will continue to shut off.


hi from uk make sure you push pump nozzle fully in tank filler as there is a flap just below filler that has to be opened fully to allow fuel to flow unrestricted ?? also considering age of vehicle ? check under the wheel arch along side of fuel filler pipe you will see a hose attached alongside ? make sure this is not kinked or blocked up at its lower end this hose is the ventilation for fuel tank ie as you put fuel into tank you also displace air from tank there for if air vent is blocked ? fuel will be restricted fro flowing hence pump shuts off ? the pipe vent is subjected to dirt from roadway and rain spray due to its location and usually blockage is with hardened mud over time ? hope this helps ? best wishes from n/west uk

Car will not accept gas


try pulling back a little on the nozzle, the tank has an anti rolloverball in the pipe and this sometimes cause it to shut off when the nozzle is stuck all the way into the filler pipe
