How is your fuel filter? When was it last replaced?

As another poster said check the inline fuel filter and consider changing it. I cut one open (it caused a pump failure) and found it full of a very fine material probably picked up from crappy gas. I routinely change mine at about 15k miles since filters are cheaper than fuel pumps
