It depends what setup you have. Mine has the plastic push buttons that you push in then pull the fuel line off. Others need to have a special tool that slides over the fuel line, unlocks it from the fuel filter and then the fuel line comes off.
It should be pretty obvious what kind you have when you get under there and look at it.
Edit: What the post above me is talking about is removing any pressure and or fuel in the lines before taking out the lines to minimize the mess. I pulled mine off w/ OUT doing what he stated and maybe a cup to a cup and a half of fuel came out. More came out of the actual filter when I took it out then the lines; nothing sprayed anywhere. Just make sure you have eye protection on...and FYI...93 octane burns like a **** on tender skin...LOL
