Colonial Pipeline has made progress in identifying the source of a leak on its main gasoline artery and estimates Line 1 will restart on Friday, earlier than previous expectations, the company said on Thursday.

U.S. gasoline futures touched their highest levels in three months on Tuesday, after Colonial Pipeline, the largest U.S. fuel pipeline operator, said the main artery moving gasoline from the Gulf Coast to the East Coast was shut because of a potential spill in Georgia.
