One thing that I don't like is code such as the following whenever you deal with an empty container:

std::cout << std::endl << std::endl;
std::cout << "\t" << "LL-> Node (" << location << ") Not Found In The List.";
std::cout << std::endl << std::endl;

When you move your code into a class, as @πάντα ῥεῖ said, then you should probably throw an exception (You can make your own class and inherit it from std::exception) instead of couting something. Otherwise, your function is given too many responsibilites, and not all applications for a linked list have a console to output to.

The other thing I don't like is this conditional:

if (head == temp1 && tail == temp1) {
  head = nullptr;
  delete temp1;
} else if (temp1 == head) {
  head = head->next;
  delete temp1;
} else if (temp1 == tail) {
  temp2->next = nullptr;
  tail = temp2;
  delete temp1;
} else {
  temp2->next = temp1->next;
  delete temp1;
}

Notice how there is a delete temp1 at the end of every one of those conditionals. That breaks that D.R.Y principle. Make the delete temp1 unconditional.
