Digital BW, The Print

I received my MIS VM-HEX inks today and am in the midst of trying to 
get the CIS set up. However, after getting two carts filled for my 
1280, both nipples for the vacuum pump have broken. I didn't have 
this problem when I first installed the CIS with other inks a few 
weeks ago.

I've emailed NoMoreCarts, but thought I'd also ask here if anyone had 
any suggestions where I should go to look locally for replacement 
nipples so I can finish this installation yet today. I live in 
Indianapolis, so I should be able to find them somewhere, but I'm not 
sure where to start looking for something like this.

Thanks...

Tom
