The average price of a gallon of unleaded fuel moved slightly higher, mostly due to a pipeline disruption in the southeastern U.S., AAA reported.

The per-gallon price as tracked by AAA increased 3 cents to $2.21, while the average price increased 2.3 cents to $2.225, according to data from the U.S. Energy Information Administration.

As a result, the average price is 10.2 cents higher than a year ago, according to the federal data.

Higher prices have come following a leak in Line 1 of the Colonial Pipeline in Alabama that drove prices higher in Georgia, North Carolina, South Carolina, and Tennessee. The line can carry as much as 1.2 million barrels per day from Houston to Greensboro, N.C.

The biggest weekly price increases came in Georgia (21 cents), South Carolina (13 cents), Tennessee (13 cents), North Carolina (11 cents), Ohio (11 cents), Indiana (10 cents), Alabama (7 cents), Delaware (7 cents), Kentucky (7 cents) and Hawaii (6 cents).

The Lower Atlantic region saw the sharpest increase with a 7.7-cent increase to $2.172, according to the federal data. The region is the only one among the nine regions tracked by the EIA that's now higher than a year ago (by 6.5 cents).

Average gas prices are below $2 per gallon in six states today including: Mississippi ($1.96), Texas (1.96), Missouri ($1.97), New Jersey ($1.98), Arkansas ($1.99) and Louisiana ($1.99).
