Here it is....Not much. 2 "o" rings (1 small,1 large), a cone shaped piston and a spring. With a small pin bent on the end, pull out the first "o" ring, with small hemostats extract the piston and spring and then the smaller "o" ring. I also found what appears to be a curved 1/2" long piece of hair. How bout that......I wonder whats in the one thats on my plane now. Guess I will do a little excavation and see what treasure I can find. (Upon closer inspection, the hair like strand might be plastic or nylon).
