A certain power bureau needs to inspect the power lines in the urban area. The inspection team travels by car from point $A$ to inspect the power lines on the east-west road and finally arrives at point $B$ in the evening. If traveling east is defined as positive and west as negative, the travel records of the inspection car for that day are as follows (unit: kilometers): $-4$, $+7$, $-9$, $+8$, $+6$, $-5$, $-2$, $-4$.
1. In what direction is point $B$ from point $A$? How far is point $B$ from point $A$?
2. If the inspection car consumes $0.5$ liters of fuel per kilometer, how much fuel is consumed when the inspection team arrives at point $B$?
