Other Fuel System Hoses Lines/piping, And Fittings Problems of Hyundai Accent

The gas tank will not accept fuel at a reasonable flow from a pump. It trips the shut off early. Sometimes fuel splashes out when this happens. Many Hyundai cars have this problem. From research, I found the following problems: 1) charcoal bits in the vent lines from the carbon canister- one owner cut open the canister and found a foam filter like in a window a/c that was damaged by gas allowing carbon to go into the vent lines clogging them and not allowing the tank to vent. Incompatable material used. 2) faulty check valve at the inlet of the gas tank does not open fully when refueling causing gas to back up the filler neck. 3) defective "sampling pump". This is in the vent system between the fuel filler pipe and the rear bumper. Pump does not operate when it should. 4) small filler tube. Gas pump nozzles in the uk had to be changed to a smaller size so that there could be some venting. The vent lines in my car seem clear. I am changing the check valve, and I will see if this improves the situation. It also seems that the Hyundai dealers do not understand the problem and what causes it.
