Why do my FPs seem to run dry quickly?

[mjm700]

Wondering if I am doing something wrong or not getting a full refill on my MB fountain pens. I can't really quantify or provide a good measure since I switch pens often but my FPs seem to run dry very quickly. All of my FPs are MB so can't compare by brand.

Rather than try to confirm my experience, it would be great to just hear some of your recommendations on how to ensure you get a good refill and what you do to maintain ink during use -

Do you frequently flush out with warm water when you refill? Anything to be careful of?
Do you dip the nib in the ink to a certain level when filling?
Do you clean the nib a certain way after you refill to avoid loosing too much ink?
Are you diligent about replacing the cap during use?
Any other recommendations or frequent causes of running dry too early?

Thanks for any thoughts.
