CNG pumps across Mumbai and neighbouring areas witnessed long queues for the second straight day on Tuesday, as supply disruptions caused by damage to a key gas pipeline continued to hamper refuelling for vehicles.

Most CNG pumps, including those operated by Mahanagar Gas Limited (MGL), saw long queues from early morning, particularly of black-yellow taxis and autorickshaws, with several drivers reporting wait times of three to four hours, compared to the usual 15 to 30 minutes.
