Old Gas Pumps Can't Rise Above $3.99

REARDAN, Wash. <br/>May 13, 2008&#151; -- Mom-and-pop service stations are running into a problem as gasoline marches toward $4 a gallon: Thousands of old-fashioned pumps can't register more than $3.99 on their spinning mechanical dials.

The pumps, throwbacks to a bygone era on the American road, are difficult and expensive to upgrade, and replacing them is often out of the question for station owners who are still just scraping by.

Many of the same pumps can only count up to $99.99 for the total sale, preventing owners of some SUVs, vans, trucks and tractor-trailers to fill their tanks all the way.

As many as 8,500 of the nation's 170,000 service stations have old-style meters that need to be fixed &#8212; about 17,000 individual pumps, said Bob Renkes, executive vice president of the Petroleum Equipment Institute of Tulsa, Okla.

At Chip Colville's Chevron station in this eastern Washington town, where men in the family have pumped gas since 1919, three stubby, gray pumps were installed when gas was less than $1 a gallon. They top out at $3.999, only 30 cents above the price of regular gas at Colville's station.

"In small towns, where you don't have the volume, there's no way you can afford to pay for the replacements for these old pumps," Colville said. "It's just not economically feasible."

The problem is worse in extremely rural areas, where "this might be the only pump in town that people can access," said Mike Rud, director of the North Dakota Petroleum Marketers Association.

Demand for replacements has caused a months-long backlog for companies that make or rebuild the mechanical meters &#8212; and that's just for stations that can afford the upgrade.

For many station owners &#8212; who, because of relatively small profit margin on gas, aren't raking in money even though gas prices are marching higher &#8212; replacing the pumps altogether with electronic ones is just not an option.

"The new ones run between $10,000 and $15,000 apiece," Colville said. "It's an expense that's not worth it."
