Hey guys. My car is a 2004 Mazda 3 Sedan. Basically, the issue I'm having is that when I attempt to fill up (regardless of how much fuel is in the tank), the nozzle clicks off after 3-5 seconds. This began happening about three weeks ago and is rather annoying as it takes me almost 10minutes to put in $20. I've tried putting the nozzle all the way in, barely in, with various pumps and at different gas stations but the same thing happens over and over. That leads me to believe that it's being caused by a problem with the air vent system that allows the air in the tank to escape while being filled. I know it exists, I just don't know where or how I would go about 'checking' it. Any other ideas or help in general would be greatly appreciated. :)

Chad

Thanks bud, just to clarify something from the thread you linked.

Except this cylinder is open on the bottom side and there is a cartridge type filter inside this cylinder housing. So I removed the bottom of the cylinder housing and removed filter. It was clean on the inside and filthy dirty on the outside and very wet.
You mentioned the outside of it was dirty and the inside clean...what exactly did you do to it before going and filling up again? Just clean it?

Hey hipshot, it was me that had the filling issue like you. I removed the filter and just stuck a small rag in the cylinder to block anything big from getting in but not enough to block the air from getting out. I've been driving it that way since last Saturday with no issues at all. I called the dealer and they could not tell me what it was called. Their system called it a "gas tank hose" because you can only buy the entire hose from the filter all the way to the front of the tank. and it's $77.00. I assume the only thing that filter does is reduce the amount of gas fumes maybe. It's just a small paper filter. I'm not sure what else it does. ControlFreak suggested i read about the purge valve and charcoal canister but I think(from what I read) those are either under the hood or on top of the gas tank. When it warms up I am probably gonna clean the filter with a toothbrush and put it back and see what happens. or maybe I'll just keep the rag in it. It seems to be working fine. Maybe my car will catch on fire and burn to the ground. That'd be sweet. lol.....
