If we assume that the average gas tank is half full, and then a large number of people decide to top off their tanks, that could be a huge amount of fuel, right?

That just moves up demand for the next week into the next two days. It's a spike but not that much.

In 2016 SC had 1.8million vehicles, maybe 75% of them pump an extra half tank (~~8 gallons?)

Call it 10m gallons extra, and I think the pipeline transports 100m gallons a day.
