Solution: (1) See the meaning of the problem.

+ 14+(﹣9)+8+(﹣7)+ 13+(﹣6)+ 10+(﹣5),

= 14+8+ 13+ 10﹣9﹣7﹣6﹣5,

= 18,

∴B is 0/8m away from the starting point A/KLOC, and B is in the east of A;

(2) The assault boat consumes 0.5 liters of oil per kilometer, and the fuel tank capacity is 29 liters.

∴0.5×( 14+9+8+7+ 13+6+ 10+5)﹣29=7.

We need to replenish 7 liters of oil on the way.
