refrigerate hose, ripped and missing

[anaisdog]

I just discovered, for my c34 1986, hull 99, the refrigerate hose foam is ripped, underneath the oven, and completely missing, from the wall of the aft berth to the Adler Barbor, in the aft lazerrette.  I don't know if it was ever covered or if it should be.  ideas?  should I cover it with foam from home depot, for house refrigerator?

thanks
