Difficulties with filling the tank all the way up

Part of the problem seems to be the overly high pressure used by some stations. I buy at two stations here on the same street, but one day I was closer to one on the other side of the highway. CHRIST that thing was so high there was NO WAY it was going to work One of the attendants said, "people complain all the time, but the owner won't fix it"

I wounder?? if you could fabricate a special fitting, AKA a large enough tube to accept the nozzle say, 9" to a foot long, with a piece of soft ?maybe? clear tube to insert under the the split in the filler tube (lower path) and built so that it would allow air out around the neck opening (for the upper path which vents)

Many people think the tank vent---the 1/4" tube--is the problem. IT AIN'T. The only way you could fix that is if it was huge, perhaps 1/2 or larger, and high enough that fuel would not be forced up into it
