Terry,
Wrapping the hose directly with the heat tape won't hurt it--doesn't get hot enough to hurt the hose. I did this a lot in WY winters. But, the hose and tape will need to be wrapped in some manner with insulation that will keep the heat tape heat in. Use a small heat lamp or a large light bulb in the service bay and leave it on all the time, and have the hose and heat tape up into the bay. I have not used the foam tubes with the heat tapes--do not know how that will work.
PVC pipe or wood box would work for cover, what ever you want to do.
Have you anticipated any power outages? Ice storms can be nasty up there...
Also, for an option, there are hoses available with the heat tape already included--pricey, but they work.
