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??

Re: Gas Tank Blockage
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 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)
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.
The fuel level gage is in the tank, but it cannot shut off the gas pump. The pump shuts off because the baffles in your filler pipe back up the gas, or possibly because your charcoal canister or vent valve is blocked. Try turning the gas hose sideways or upside down when filling. If that doesn't work, have a good mechanic check your evaporative emissions system for blockage.
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
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....
There is an anti-syphon screen in the filler neck of the gas tank. They do not have very large openings and the slightest debris will act like it is blocked. EIther have the screen replaced or completely removed, or don't put gas nozzle completely in the hole
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
