I don’t remember where I originally came across the file — I’m guessing it was either here or on one of the Atlas Yahoo groups sites. Fortunately, I printed it out at the time and added it to my Atlas paperwork. The printout I have isn’t the greatest quality, but I’ll see if I can scan it somehow.
I picked up a second MFC the other day and it has the pump. But I think it’s been modified a bit.
