Okay, so I'm frustrated. Every time I pump gas the truck simply will not take it. I cannot pump more than one dollar worth of gas before it triggers the overflow guard and comes spewing out of the top of the gas hole, dripping down the side of the Rover. Is this just a Disco thing, or does it seem there is some sort of blockage preventing gas. Every now and then it will take gas fine though. Any help is appreciated, thanks

 

Your fuel breather tube is blocked.
Look under the truck, it is the small tube that runs parallel to the fuel filler.
