Yep. I usually plug both ends and shake it up, then see what comes out. The sediment usually settles at one place.

There should be a schader valve on the injector fuel rail for releasing the fuel pressure. I don't like running engines out of fuel if I don't have to. Personal preference.

I prefer not to spray gasoline all over the top of my nice clean motor

I never had pressure issues when I changed a fuel filter on any vehicle, I usually change filters after the vehicle sits for a while though. I've pulled the fuel pump fuel and ran the truck out of gas and didn't notice a difference in amount of gas that dripped out compared not running out of fuel. The filter holds most of the gas that drips all over the place.

after reading this thread i decided, after 130k mi, i would change my fuel filter. thinking i would find all kinds of crap in the filter, i cut it apart. to my surprise the thing was clean. i mean the paper was slightly discolored, but there was no sediment. for the most part i would have called it good. i am not saying waiting this long was smart, just that there seems to be cleaner gas in different regions.
