More gas tank troubles

[pacodiablo]

My Explorer had a badly leaking gas filler neck that was completely rotted out from rust. I found a replacement in very good condition (no apparent damage at all), and had it installed at a reputable local shop (apartment complex frowns on parking lot repairs), but I am still having issues with gas pumps clicking off and not allowing me to fill the tank. I'm gussing my problem is now somewhere other than the filler neck since I do not smell gas around it anymore and I can't see any visible leaks like I used to. Also, the filler neck on this truck connects to the tank with quick disconnects, not hose clamps, so it should have a good seal. Does anyone have any ideas of what to check next? Something has to be leaking somewhere for this to be happening, right? I can fill the truck up, but I have to hold the nozzle of the pump out from the filler a little bit. It is annoying to have to fiddle with it and get it in just the right position to pump gas.

If the air line that vents the tank is not working correctly it will not let the gas fill as fast as it needs to. Therefore the gas backs up into the fill neck and kicks the pump off. I would check to make sure there is not a kink in the smaller vent tube.

AFAIK, a leak would not cause the symptoms you are describing.

I agree. They didn't install the neck properly, kinked or plugged the vent hose.
