If you are intending to do the DIY thing for a while I suggest using these in your caps.
I used them for years when I did DIY and never had a leak.
They are dirt cheap, in fact the shipping costs more than the items, so buy a few packages. I'm not sure, but you might even be able to find the tubing mentioned earlier on this site:
