Neighbor's kerosene tank makes horrible noise at night
My neighbor's kerosene tank makes a rather high pitched humming noise when her furnace is running. It's driving me crazy at night when it seems to get much louder. She recently had her furnace replaced but the tank is very old. What could be causing this?

The oil lines that run from tank to furnace is acting like a guitar string. As oil is being pumped through the pipe, it is humming. Try placing an old rug on the tank to see if it absorbs the hum.
