Cool and dark or w little light I suspect.
Wouldn’t think a hose would need a special place.
But I think common sense would store them well.
I have mine under the seat of the setee.
Dan,
Tell them you did what?
If you have a vacuum food sealer, the bag is endless, so larger items can be sealed. Rubber products evaporate solvents as they age and excluding air slows the process. Also a good way to store spare parts. You can buy moisture absorbing products online to include in the bag.
I keep new spare water pump seals, bearings and other long term items in vacuum sealed bags. Even big things like raw water pumps and alternators.
