power steering hose and light bulb ?

[Daves72'GMC]

I've got a 72' GMC with the 402BB, which I'm restoring which has the power steering pump with the separate reservoir. I need to replace the larger hose going from the pump to the reservoir. I noticed at the bottom of the reservoir is a little smaller fitting than at the pump fitting where the hose goes on. I've heard in the past it takes a special type of hose.The parts man wanted to sell me regular heater hose which I had on it and it swelled.What kind of hose do I need and what size is it? I also need to replace the bulb which is on the outside cab light over the back window.The number on the old bulb has GE 94 on it.I checked the auto part store today and he said he didn't have one like it and the GE 94 # doesn't cross over to any other bulb.Does someone know what bulb and part number I need? Thank you everyone for your help.
