NEW YORK -- Gas prices rose Friday for the 45th consecutive day as summer travelers hit the highways and refineries hold back on fuel production, according to The Associated Press.

Pump prices added less than a penny overnight to a new national average of $2.639 a gallon, according to auto club AAA, Wright Express and Oil Price Information Service.

Crude prices are surging as well, but not as consistently as gasoline.

Benchmark crude for July delivery fell 64 cents to settle at $72.04 on the New York Mercantile Exchange, the first time oil prices have fallen in several days.
