These are vacuum fill, so they are designed to pull a pretty strong vacuum just to allow the initial filling. I think there is a video of the proper way on the company's website (http://www.inkjetcarts.us) so applying a vacuum of some sort should be fine. Best would be putting the whole cart in a bell jar and pulling that down to vacuum but I don't have that type of rig.

And as a whole these carts are only OK, out of 18 carts I have a couple of dead chips, and a couple carts that either leak or are too restricted and cause missing jets., But the are cheap at about $22 for a set of 6. Buy enough and you'll have what you need to get going while you wait for exchanges.
