power steering pump? I effing hate my truck

Only sometimes though. The other day I started my turd about 15 mins before I was gonna leave. Got in and started to back out of my space and WTF...My steering wheel is effing hard to turn. So I back straight into another parking space to see WTF has gone wrong this time. When I pop the hood I see that the whole drivers side of my engine bay is splattered with power steering fluid. Rode with a buddy to lunch then checked it out when I got back and found that one of the lines slipped off the tube that goes to the mechanism on the steering shaft.
I know that it's not a big deal to take care of but it was -22 ambient outside this morning.

I guess my question is will anything get FUBARED if I drive it back to my house. ~2 miles at 20mph

you'll probably ruin the pump running it dry.
