Customer: replied 5 years ago.
Dan, thanks for getting to me so quickly with specific guidance and all the great figures. Do I really need to disassemble all the formentioned "stuff" or can I just skip down to the 3-2 solenoid replace and seal it back up?
Customer: replied 5 years ago.
Many of the hyperlinks in your article are inaccessible, particularly the one pertaining to the reset of tap values (which will be most helpful when I finish). Is there another way you can transmit the info to me so that I can acutally use it?
Expert:  Dan replied 5 years ago.
Yes, you can skip down to the 3-2 solenoid replacement and let me see about getting that hyperlink ok.
