Why you ask? It's not the seal, or the o-ring or the hose or clamp, according to them. I will replace the reservoir o-ring anyways.
I asked only to find out who determined the need for a new pump. Try following the instructions in this TSB from M/B. Without the engine running, turn the key to positon #2 and turn the steering wheel from stop to stop at least 30 times in an attempt to purge air from the system. It would be much easier if the front wheels could be lifted off the ground. I don't know if it will work, since the truck has been driven already, but it's worth a try.
