Are you planning on the computer cranking to reset or are you just going to set it at zero and disconnect it? If you are doing the later, you need not dis-assemble it. Simple rotate the numbers until you get the correct ones you want facing front. If you want the first option? Most of us use either Joe Yokum or Tom Buckles, both are on here, for computer rebuilds. Both are very qualified and your computer will be perfect upon the return. Paul www.severngaspumps.com
