Friend has a leak down near the rack and pinion. Can he drive and refill the reservoir until he gets home? Leak is in the lines down by the r and p. If he can slow the leak down and then top up, can he drive and still have the vane pump survive? Other possible damage? It's a 2008 2.7L manual Tacoma xtracab. My truck is not the same so I don't want to tell him the wrong things.
