[C320-list] Changing Racor Filter

[jonvez at comcast.net]

Al, is this the large one on top? I thought that was the pump. When I change filters, I unscrew this completely and use it to pump. If it is the shutoff, do you turn it part way? Or is there another screw you are referring to?

Regards,

Jon Vez
