Crawled back under there to be sure there were no leaks, and none were visible, I went ahead and pulled my EVAP nylon tube off, and brought it in to see how well the rescue tape would work to seal it, and it worked perfectly, I am impressed with it.
For the longest time I had wondered why I'd stopped hearing that sound of a little pressure being relieved when I'd open the gas cap, and now I am pretty sure I found out why, that EVAP hose not only had several holes in it, but needed the soft rubber part that goes from it to the tank replaced, I had some soft rubber fuel line hose left over, so I used it to make the new end, and affixed it to the metal part of the EVAP line at the tank, I won't be driving for a day, or two, but when I do I'll report back on whether or not the gas cap starts making that old familiar sound when removing it.
I even figured out how and when the line was damaged, it was due to my old rear struts airbags being dry rotted/cracked, I went to petsmart one day, and backed in, I had my rear end protruding over the curb quite a ways, I came out to find it sitting really low in the rear, and when I drove off it scraped the curb, it would partially raise up, and I thought it had raised up enough..
