I got a single sheet of Label "Pull" Red Adhesive backed from R-Jet Tek, but haven't tried it yet as something to put over their #1916 inlet port plug .Redbrickman said:Try and find thin aluminium adhesive tape.
They also have adhesive round dots made of mylar that I'm interested to try. I think Rapid-Refill uses these, with a rubber ball underneath, within the inlet port. Haven't tried them yet, and seems a bit pricey for what little they are.
