DICKSON, Tenn. -- The money crunch is felt every time you go to the pump, but people who have old pumps are also getting pinched.

The money crunch may also make some hard-to-find classic gas pumps disappear forever.

Mary Helen Meadows and her family have owned a gas station and store in rural Dickson County for 25 years. Her house is next door.

The old-style pumps feature a dial with numbers that appear in a window, instead of the digital readout, which is now featured on more modern pumps.

"Well, I sell gas and I use gas, and I think it's pretty rough," she said.

On the old pumps, the price per gallon only goes up to $3.99 per gallon. And when customers pump diesel, they are told of the $4.36 price with a taped-on sign.

"If it goes up again, we'll probably have to redo our pumps or buy new pumps," Meadows said.

Having to buy new pumps could put some of the privately owned businesses out or force them to give up selling gas.

The cost for new pumps can cost anywhere from $10,000 to $30,000. Upgrading the old pumps would cost between $700 and $1,000, but that could just be a temporary fix and the upgraded equipment won't likely be produced much longer.

"Might just give it to the gas company and forget it, or take them out," Meadows said.

For those gas pumps that can't keep up with the rising prices, the state is requiring upgrades or replacements after a grace period.
