Remove the one with the flap that is closest to the end of the cart.  
It's the air intake.  Ink can't exit the cart with the air intake 
blocked.

Recall also that commercial carts are vacuum filled.  As such, these 
plugs should be removed before the carts are installed.  Otherwise, 
it's possible air will be pulled into the cart through the outlet 
when the cart is installed and the outlet seal is broken.  So, you 
may have air in the outlet that will need to be removed.  The fastest 
way to do this with with a bottom fill adapter and a syringe.

The bottom fill adapters are $0.50 items from MIS.

A sharp scissor can cut the bevel on the end.

Good luck with the system.
