CAMARILLO, Calif. (AP) — The average U.S. price of regular-grade gasoline jumped 4 cents a gallon over the past two weeks to $2.26. Industry analyst Trilby Lundberg of the Lundberg Survey says Sunday that a rise in crude oil prices spurred the increase. The price at the pump is 35 cents less than it was a year ago.  The highest average price in the nation is $3.34 a gallon in San Francisco. The lowest average is $1.81 in Houston. The average price of diesel spiked 6 cents over the past two weeks to $2.58. The survey was conducted Friday.
