I the filter is on the drivers side frame rail to the rear os the transmission cross member.
You must release the fuel pressure in the fuel line or gas will literally spray everywhere. On the passenger side fuel rail (on the engine), there is a Schrader valve which you can depress and it will de-pressurize the lines.
Use a K-D 3321 fuel line tool, available at various auto parts store for around $12. Use the smaller 5/16" end.
Note the safety clip on the end of the fuel line where it mates to the filter. Remove this by squeezing it together and unhooking the small latch. Your new filter comes with new clips, but I prefer the factory issue as they're somewhat sturdier so I always save them.
After you've removed the safety clip, slide the fuel line away from the filter so you've got enough room to insert the tool. On this particular vehicle, one of the fuel tank interfered with my using the tool, so your going to slide the filter partially out of the bracket to gain access. No big deal. Push the tool in to the fuel line (away from the filter) and listen/feel for a click to indicate you've disengaged the locking device from the filter.
Once you've disengaged, pull the line away from the filter. At this point you'll start getting some fuel draining out. I like to take the dust cap from the new filter and place it over the discharge end of the old filter to control the mess. Try to move the fuel line so that it's raised to minimize fuel leakage from there as well.
Then moved on to removing the fuel line from the inlet side of the filter. Note the "teeth." These are springs that lock on the raised flange of the fuel filter. When you insert the tool to disconnect, you are pressing in on these springs.
When you're ready to install the new filter, insert it into the bracket and press the fuel lines on to the new filter. Just as you felt/listened for a click when removing the fuel lines, listen/feel for a click during installation.
After you've hooked the fuel lines to the new filter, install the safety clips and you're done. It's that easy.
Good luck and hope this helps.

There is a special tool used to disconnect the lines from the fuel filter. You should be able to get them at any local automotive shop, i.e., Pepboys, Autozone, Chief Auto. It should be relatively cheap to buy this tool.

unbolt the filter from the bracket, that is a 5/16" machine screw head size, then remove the nylon clips that hold the lines onto the filter, hold a rag over the fuel line when u remove it, it will have about 30 pounds of pressure.
