Default Problem: Re-fueling problem

In my '95 Hardbody, 2.4L, re-fueling or putting gas in the tank has been getting harder. When the nozzle is inserted into the fuel filler opening, it seems like pressure is building up and the pump will click off frequently. Sometimes, when the gas in flowing into the tank, some gas seeps out of the small hole in the gas filler rubber accordion boot. Seems like the tank is not venting properly when the gas in flowing into the tank. Is there something I can replace?

mine will do that if the fuel nozzle is shoved all the way in with the trigger pulled for max delivery speed. i just stick the nozzle halfway in and let it go wide open. it doesnt take no time at all to pump 12 gallons of gas anyways.

and that small hole is the vent tube. with the fuel going in faster than the tank can vent the air, the fuel will back up in the main fill neck and shut the pump off to prevent spraying.

I also found a that the rubber fuel filling tube, the main one, was cracked at the top. I could only find a universal piece of fuel filler hose at Napa Auto Parts. The diameter is between 1 5/8" and 1 3/4", 1 3/4" hose is slightly too big. Once I fixed the hose, it seems to fill better now. The first time I the vent was still clogged and it was hard to fill, but better. The second time it filled up almost perfectly without any over pressure or spillage. I will try 1/2 way insertion if I have more problems.

Follow up:

After a little more research, the '95 HB has a charcoal canister between the spare tire and the back of the gas tank. When you fill the tank with gas, since the nozzle is sealed to the filler opening, the gas tank must vent the air through the charcoal canister. The charcoal scrubs the venting air of hydro carbons. After some time, the charcoal filter in the canister will clog and will make it hard to fill the tank up without the pump turning off.

I ended doing a cheating fix. There is a small vent hose that runs from the top of the gas filler to the tank. I ended up putting a brass tee fitting on this hose then putting a check-valve on the outlet of the tee fitting. You could eliminate the check-valve, but you will smell gas if you park in a garage, in additon, dirt can enter the open side of the tee-fitting without a check-valve.

To clarify, the later '95 trucks have the moved canister. My 2/95 HB still has an under hood canister. What's the build date of your '95?
