Filling gas tank
I have a new Four Winds Class C on a Chevy chassis. I cannot get gas into the tank. I can only get 0.01 to 0.02 gallons to flow before the pump shuts off. Has anyone had this problem? I am...

The motorhome is new (750 miles when the problem showed up). I have only once filled without a problem. This was at a gas station with old pumps. Probably slow flowing and less sensitive.
Yesterday I was able to get under the motorhome.
The filler tube is metal and a smaller metal tube for venting runs down the side of the larger tube. It is then attached to a rubber tube that bends up and to the top of the tank.
I disconnected the rubber tube and gas ran out.
It is obvious that when the gas builds up in the fill tube it overflows into the vent line and accumulates at the bend in the vent line.
I am on the road and not able to make modifications but I would think that if I cut off the metal vent line and attach the vent to a rubber line that goes up and then down to the tank that gas cannot get into the vent line.
I am going to try disconnecting the vent line and then fill up the tank. If I am correct, the problem is strictly with venting. The problem is that I can't leave the vent disconnected until I get home.
If the experiment works, then I will probably have to pay to have the vent modified.
It looks like Four Winds (Thor) has never designed a motorhome fill/vent system in the past.
