I would drop the tank, give it a reseal kit and blow out the vent line that
goes from the top of the filler neck and into the top of the tank.
When you fill the tank, there is no perfect seal from the nozzle on the
pump, so air should be able to vent while filling it up. At the bottom of
the fillier neck, mine has (about) a 3/4" ball in a cage that's part of the
filler neck, to keep fuel from backing up the filler neck (I guess on hard
corners or roll-overs). I suppose it could be that this ball is stuck in
some way, blocking the entrance of fuel at the bottom of the filler neck.
Can't think of anything else, unless you are using the same pump at the same
station and it has to do with the pump and not your van?
