You anwsered my question which had puzzled me for long time. Thank you very much. I was told that when I replace the rubber O-ring and the brass washer of the delivery valve, if it becomes noise, I should retorque it. I did not know why I had to retorque it until now.
I really cannot say enough how much I appreciate the time you spent on helping others.
