Should the tube that carries the evaporated refrigerant
back to the compressor be hot while running?
I just re-insulated my supply side line with foam covering and aluminum tape. I enclosed part of the tube that carries the evaporated refrigerant back out to the compressor and noticed that this line runs hot.
If running hot is normal then I most likely should have it exposed to the outside air as much as possible right and not covered?

One line is hot, the other cold when the compressor is running. Normally only the cold line is insulated.

They run pretty close to one another. Through the same opening into the home wall. I'm thinking I can pull some separation between the two without doing much damage

Yes, you want to separate the two lines as much as reasonably possible. The reason for insulating the cold line is to minimize "sweating" (condensation), particularly where it enters the house wall (don't want to get the inside of the wall wet).

Since I can't follow the line inside the wall run there is a aluminum cone (or sheet metal) that these lines run into at the base of the outside wall then up inside the wall. I'm going to assume that this sheet-metal wrap runs up the inside wall a decent distance to run-off any condensation that may occur?

Depending on how efficient ( SEER rating ) the small / liquid line should be anywhere from hot to barely warmer than ambient temp .
Large / suction line should be pretty cool to cold . And WELL insulated .
