Sounds like the tank vent is malfuntioning or you have a faulty gas cap.

How to replace a fuel tank vent valve


Fuel tank venting is handled by the EVAP system, which includes a vent valve (on the cross-member to the rear of the tank), a canister (behind left rear wheel), a purge valve (on the engine), and several hoses.
If you are having a problem with this system, start by checking all hose connections and then the vent valve (this valve picks up a lot of road debris and usually fails first). Unless you are actually seeing gas on the ground, a gas smell is often caused by this vent valve sticking open.
Another problem can be the canister filling with water/gasoline due to a failed purge valve. And so on.

Why I can't fill gas tank on Subaru Forester? It shut off as if the gas tank is full .


the vent control valve on the charcoal canister is clogged or stuck preventing the air to escape from the gas tank causing the gas to back up in the fill tube and shut off the pump. if this is the case your check engine light should be on... P1443 indicates a problem with the evap vent control solenoid valve. some auto part stores will get the codes from your vehicle for free and tell you what could be causing it. although you have to be careful some codes can be caused by one thing and be the cause for the code on another part. an example is your problem, a clogged vent hose from the gas tank to the vent solenoid can throw this code or it can be the valve itself.

The car seems to have an obstruction in the gas line, won't take gasoline easily from the punp. Turns pump off continuosly.


Dan the reason it takes it from a gas can is there is no pressure building up in the line as you would have from a gas tank. As you fill the tanks the air inside of the tank has to go out as the tank fills up. I would suggest checking the fill hose thats connected to the gas tanks and the spout inlet where you put the hose to fill the tanks and check for kinks in the hose. Second there should be a vent hose from the tanks that connects to the spout also check it for kinks or blockage this would prevent air from escaping from the tank causing the gas pump to cut off due to the rapid filling of the tank without the air being able to escape. Hope this helps

Service engine soon light came on, replaced gas cap it went off but a week later it came back on, when it try to fuel the truck it spill the gas back out like it is a full tank


One of the most common causes, is blockage in the venting system from fuel entering the vent lines and into the charcoal canister, the fuel gets absorbed by the charcoal canister causing it to swell and block vent lines. the gas tank contains both fuel and air. when you fill it up the gas displaces the air and the air has to go somewhere. but the air that is displaced is full of gas vapor so the gas vapor goes to the vent lines and into the charcoal canister, when the charcoal canister swells up it prevents the air from escaping the tank, canister could be clogged,canister filter may need replacement,electrical connection to the close valve may be open,canisterf might be damaged,purge valve from canister might be clogged,vent hoses might be clogged, the vent hose could be clogged, or the vent hose may have a kink. all this is caused by overfilling the gas tank, getting that last drop of gas in the neck of the fill tube.
good luck!

2004 mercury sable gas go's into tank real slow


This is caused by an obstructed filler air pipe vent, this keeps the air from coming out of the tank as you fill, this causes the filler nozzle at the station to shut off as the gas backs up in the filler pipe, the air vent pipe is either kinked or blocked in some way. The vent tube runs down along side the gas fill tube and is all one part, replace it.

When I go to fill up the gas tank the gas keeps cutting off at the pump handle and I have to slow the gas pump to a trickle in order to fill the tank.


The problem is that your gas tank "pushes back" like it's full even when it isn't and makes the fuel valve click off. Tom and Ray on Car Talk covered this in a 2007 show and I pasted some of their response below:

"RAY: This condition is probably caused by either a blockage in your gasoline vapor recovery lines or a bad refueling control valve.

TOM: Gasoline vaporizes. How do we know that? Well, when gasoline is spilled, you can smell it, right? What you're smelling is vaporized gasoline.

RAY: And in the old days, when you filled up your tank, all the air inside the tank -- the air filled with gasoline vapors -- came whooshing out through the filler hole or through a vent at the top of the gas tank.

TOM: But then people in places like Los Angeles realized they couldn't see the person standing next to them due to smog. And since gasoline vapors contribute to smog, car makers were forced to install devices to capture those vapors.

RAY: So now each car has a vapor recovery unit that collects the gasoline vapors from the tank and then, the next time the car is started, sends them to the engine, where they're combusted. Your vapor recovery system isn't working, Lottie. One possibility is that one of the rubber hoses is blocked or collapsed."

Smell of gas when filled over half


Likely to be the gas tank vent hose that allows air to escape from the tank when filling. Probably located somewhere along the trail from the filler tube to the tank and likely to be difficult to reach. The connections get loose and the hose falls off sending fumes into the passenger compartment.

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


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

Unable to pump gas


This problem is caused by the fuel tank vent pipe being restricted, usually it is kinked, replace the filler pipe vent.

Filling gas tank


There is a vent pipe that runs along the fill pipe, they get kinked and cause this concern (tank can't vent air when filling), the only fix is to replace the fill pipe assembly.
