Can't get gas to go in tank, and it will spit out gas

For a few weeks when we pumped gas it took a long time to fill it up, now when I tried to fill the tank up, it would only take like 2 cents at a time, and then it would spit out gas. So I can't get my tank filled up with gas without wasting alot of gas coming out of the tank. What can we do, and how costly is it? Whenever I try to pump gas it just spit it back out..I'll get about 10 cents before it spits it out..what causes this and how can it be fixed?

    there is fuel filter installed in the filling tube, just before the tank.

    take a look under the car, from the fill tube to the tank.

    every car, every year, the manufacture change the location and the method how the filter is installed.

Every gas tank has a vent tube, so when you fill the tank, air can escape, while the fuel is being pumped into the tank. Some vent tubes are metal, some rubber. Yours is either collapsed or plugged up. Look at the fill tube in the firebird and follow it from the gas cap to the tank, there should be a 2nd smaller tube that is your vent tube. Check to see if it's collapsed, pinched, or bent. This is definitely your problem. Check out this web site for pictures of different fill and vent tubes to get an idea of what to look for. Good luck let me know how you make out. Curt

There could be a number of things wrong, but it all has to do with fuel tank pressure. You may have an issue with the canister vent/evap solenoid. It is not allowing the vapors to vent into the intake which also helps with ignition. It is under your hood and connected between the fuel line and the intake. Could also be your purge solenoid, and sometimes, your purge canister. Replace your vent solenoid first, as it's easy to get to.

SOURCE: can't get gas to go in tank, and it will spit out gas

there is a breather pipe running long the filler pipe, if u look at the furl cap there should be a small hole that lets out air as u fill up, i think that this is blocked .

2003 kia Sorento gas keeps spitting back out when I try to fuel up


There's usually a flap on the fill tube below the gas cap. Try to put the pump handle past the flap, and slowly pull the pump handle to fill the tank.

Can't put gas in my 2004 Pontiac Grand Prix


I doubt it.
Usually the problem is a blockage in the fill tube, sometimes the vent for the tank is not working. But there are several components to the EVAP system.
I would check the filler tube first.

Every few cents the gas pump clicks, no fuel gauge


Could be the fuel tank breather is blocked.
Lots of fuel tanks are wide and slim these days and formed to fit the body profile so they have one or more humps that are higher than the filler pipe entry. It would be quite impossible to fill such a fuel tank if the top of the hump(s) weren't vented.

Because the fuel tank these days must be a closed container except when filling, such vent pipes would be connected to a branch of the filler pipe above the maximum fuel level to ensure the tank can be filled and to minimise blowback during filling.

Won't take gaskeeps clicking off no matter where you position the nozzle


If your fuel nozzle keeps clicking off while trying to fuel your gas tank then you may have a problem with your fuel tank pressurizing and releasing the pressure. Meaning your tank vent valve may be bad or stuck closed. this is part of your cars emission system and the only real way to check it is have someone with a scanner access the system on your car and check it. A technician can activate the different valves and switches in the system, check it for codes or other problems using a scanner with the proper software for your vehicle. Something you may can do yourself is just look at the hoses going to and from your fuel tank ensuring none are disconnected, collapsed or kinked, this could cause problems also. Hope that helps.
