Pump problem

im not sure if its just my pump...but to all you other pump users out there---

sometimes do u find that your pump isnt fully "primed"? meaning theres a break rite at the end of the tubing so that you know that the insulin isnt being pushed all the way out?

i notice this sometimes and i guess at first i thought it was bcuz my pump was pretty old so it wasnt like it used to be, but i just got a new one and its doing the same things sometimes -__-

is it the way my pump is being placed??? i thought that could be it but im not really sure...

ANYBODY ELSE HAVING THESE PROBLEMS??
