First thing. Fuel tanks are part of a closed system. As in n o vents to atmosphere. After all, in this day and time of EPA, emission controls, et al, it is a mortal sin to vent gasoline fumes to the atmosphere. Therefore no conventional vent as in the past. Now, having said that, there are two places to look. As others have mentioned, the charcoal canister is the first place to look. You should be able to blow through it easily. Also look at the hoses to and from the canister. They can become blocked internally. Prolonged exposure to petroleum fumes along with ethanol fumes can cause them to deteriorate internally and become gummy. This is not always readily apparent from the outside of the hose. Make sure that you can blow through them. Last but not least. Look at your filler neck. You will see that there are TWO tubes. One large, one smaller. The smaller one serves as a vent for filling the tank. Notice that it connects to the larger tube near the top. This allows the displaced air to exit above the fuel nozzle during refueling. If this smaller hose becomes kinked or collapses internally, it will interfere with refueling. If it feels soft, replace it.

It would be a great day for the collies and the terrier dogs, rats and mice would be at the bottom of the stacks so the dogs, would have a busy time hunting and killing, all the corn was gathered and ricked in what we c
