I thought this might help some of you.

I've had fuel issues where the engine wants to die while motoring around. I saw the fuel filter looking disgusting (even though I had replaced it a little bit ago).
I ripped open the fuel filter to see what was inside--a lot of amber-colored, crystallized, plasticky, translucent flakey stuff. Check it out: http://www.youtube.com/watch?v=nt7ggbkfCnc

Come to find out, there was a bunch of junk upstream from the fuel filter.

How this junk was in there, I'll never really know. It could have been old gas?? Deteriorating fuel tank/hose/etc? I bought a new tank and hose just to be sure. I left the filter off, and just squirted gas through it to flush the hose leading up to the filter. Junk came out. Dang. Of course this would block fuel flow to the engine. No problems now (other than low rpms). Working on that issue.
