A couple days ago I was refueling the VX and noticed that the pump would cut out like it was hitting resistance(as per usual when a tank is full), however, I had only 2 gallons in the tank that I put in there from empty... I kept retrying to fill the tank and then eventually gas started spilling out from where I was filling from. I had only put a total of 5 gallons in the tank when it started doing that and I noticed that if I filled a little bit and then stopped, then it wouldn't overflow.

I can't imagine what would be blocking the gas from getting into the tank or cause it to fill slower than the pump... it's very frustrating. Has anybody else had this problem? I suppose it's been building up because I would notice that the pumps kept stopping on me in previous refuels, but I just thought that I kept hitting crappy pumps...

Any ideas as to what would be obstructing??
