Digital BW, The Print

I am getting ready to install a used  CIS (nomorecarts.com) in to a 
Epson 1160. There is still ink in the lines and the end of the tubes 
have been bent over and taped off. 

Do you think I should try and vacuum pump any air out of the line
even though there is ink in the lines or is there away  to vent  any
trapped air later?

Thanks

Steve
