Does anyoen know difficult this is? would I need any special tools, or
should I take any precautions?

When I did this on a Chevy Blazer a few months ago, there was a perssure
release valve under the hood that I had to drain before I could unhook
the fuel pump.
The pump I know can be accessed from the trunk and should be pretty
straight forward.

Anyone know where the filter is and how difficult that might be?
