Hey Tanker,
There are several places to buy authentic looking hoses. I just bought the one from Jim on this site that's has the red/white/blue stripes on it. It's New Old Stock hose, so it's not 100% white and shinny, but looks amazing on the pump:
http://stores.petrorelics.com/Categories.bokVics66.com is also a place you can get the cloth covered white hose new.
I assume you are asking what the "Keep Stuffing Boxes Tight" means? The Stuffing box is the connection between the pump shaft and the handle. A stuffing box provides a liquid tight seal around the shaft and the exterior connection with the handle - the stuffing packing material could be all kinds of things (not sure what they used on gas pumps actually) but on our boat, the shafts are sealed with a wax ring/fiber rope to keep the water out. The packing gland is "tightened" down by the nut on the exterior. My 615 has a spring inside to keep tension as the packing (stuffing) material wears down, but you always have to keep tightening the nut periodically to keep enough pressure on the packing material to stop leaks, but not so tight that you lock down the shaft.
If that's not what you meant, sorry for the long description!
