The easiest way to release the fuel pressure is to disconnect or pop-up the red button on the inertia switch, which is on the driver side inner fender in the trunk. Then just crank the engine over a couple of times until it stalls. Depending upon model year, you'll need an a/c or fuel line disconnect tool to release the forward connection on the filter. The rear is just the standard plastic clip type. First I made my own, then I found that the scissor type tool that is sold for Ford's (available at most parts stores) worked great - because you need to expand the little spring clip inside the end of the fuel line before being able to pull off the filter. There is also a big safety clip that goes over the outside to secure the whole connection. 30 minute job tops, but have a container of some sort under the filter, because even after releasing the pressure some residual fuel will still spill out.
