Fuel Filter

nope... it's more of the case that the filter would have been letting crap through and clogging and gunking up the injectors. Fuel pressure is what ensures fuel delivery and if the filter is dirty it still lets the presure build... Down and dirty elpanation.

Depressurize the fuel system prior
yeah, even after depressurizing and for safety reasons disconnect your neg. battery terminal. But yeah its not a lot of fuel as far as volume but try not to have your eyes right below it. When I did mine 3 weeks ago i was surprised at how much came out considering the fuel filter is at the highest point between two fuel lines.

. Actually when i worked at ford we recommended fuel filters every 15k... and im pretty sure that is correct. it is the same at gm where i am currently employed. you do not HAVE to depressurize. though it is recommended so fuel does not spray all over... depressurization is easy.. use a rag and press the schrader valve on the fuel rail until it stops spraying (do not have thekey in the ignition or the fuel pump will try to keep the system pressurized.
ok, this is how you get it off... put the tool in there and push it in, then pull the filter toward the tool and pull the line. should come right off, lotsa times they are rusty as hell and you have to wiggle it all around, try spraying some rust penetrant in there if its really bad...
