This woman claims the gas pump charged her for gas she didn't get.

"I clicked it down and it went to 8 cents and then I started pumping," a customer said.

It wasn't much. Just a few cents appeared on the pump before the gas started flowing, but she and others say, with the gas of price so high these days, it's adding insult to injury.

We happened to be traveling with a Florida Department of Agriculture pump inspector when this situation occurred. He says it may appear the pump is ripping you off, but that's not the case.

"The pumps are not really jumping. It's the safety valve, it's the drain valve in the nozzle and the fuel is not coming out once you pull the handle. And then it kinda bumps the valve open and they think they didn't get that fuel and that's the biggest thing I see," James Wood said.

It's Wood's job to make sure the pumps he inspects are properly calibrated. He says when a properly calibrated pump appears to jumped they're still accurate, so you're not usually getting ripped off.

"99 1/2 percent of the time there's nothing to it. More the gas goes up the worse it gets," Woods said.

If an inspector identifies a pump with problems they put the pump out of service.

"A meter mechanic will come back out and put a new nozzle on it and then call me and tell me it's fixed," Wood said.

If you notice a glitch in a gas pump you can report the problem by contacting the Florida Department of Agriculture. We'd like to stress Wood says this is not a plot by the gas stations; it just happens sometime. Over the years Florida has had one of the best records in the country for accurate gas pumps.
