Ok... There isn't anything holding the injectors in, except accumulated filth in the hole. Once you remove the crows-foot clamp, that is it. Now, the way I was able to remove mine without using the tool (Which I had, but was a monumental PITA to use) was fairly simple:
Leave the hard line connected to the injector body, snug the nut up FINGER TIGHT only, then using ONLY YOUR HANDS and not any tools, rock the injector gently back and forth using the injector line as a little bit of a handle. You are attempting to slightly rotate it in the bore, nothing more. As it begins to rotate (it doesn't have far to go in either direction) then you can start attempting to lift with a crow's foot wrench in the slot and levering against something SOFT like a cork or rubber plug as you extract the injector.
They WILL come out without too much argument. I used a shotgun-bore cleaning kit from Walmart (about $6) soaked in brake cleaner to clean out the injector bores. If the copper washer doesn't come out with the injector, there is a narrow copper bottle-brush in that kit that is perfect to stuff into the center of the crush washer and it will pull right out.
Quick question: do you disconnect the short individual injectors' fuel lines from the common rail prior to attempting this extraction method? My injectors are soaking in PB Blaster overnight, will get to them tomorrow. Thanks! A.

Great instructions, thanks geordi! I guess I still don't quite get the "finger tight snug nut" idea, but anyways. Applied copious amounts of PB Blaster 24 hours in advance. Only the #1 required a tiny bit of a help by craw's foot wrench. Then when I got to #2 and tried to loosen the fuel line nut on it, the injector suddenly moved (twisted)! After some further twisting back and forth I was able to pull it out with just my fingers (lucky sensored word!) with the short fuel line still attached. On the two remaining ones I didn't even bother to disconnect the fuel lines, just disconnected the other end of the short fuel line from the rail and started twisting the injector gently. Here is an extra "twist" I came up with: once the injector budges and starts rotating even by a tiny bit, apply yet another big load of PB Blaster to it. It immediately starts to move easier and with increasing amplitude. My theory being that twisting helps the Blaster to penetrate down and loosen the gunk there - this is of course just a theory. Once it could be twisted with just two fingers, it is ready for twist & pull, fingers only. Good thing it worked the way it did; I swear I won't be able to detach the fuel line from #4 because of the overhanging cables and the proximity of the firewall. Just my 2c. A.
