I got a response on the difference. it sounds like it's a running change...

I'm soon close..now I'm having a problem with the power steering pump. I've made sure the oil up the o-ring and have the adapters in there... but.. I connected to the pump side.. and now the head of the other side is facing left or toward the engine... since this is a hi pressure line I didn't want to mess with the head unless it's ok to do so as it's torqueddown pretty good.
