I have been getting ready to replace the fuel filter and spark plugs on my 02 3.0 X5. It has a little over 100k. I have looked at a lot of the forums and DIY's from other people. How difficult is the removal process of taking the panels off and getting to the fuel filter? Once you get to the fuel filter is it pretty much straight forward on how to remove it? Did you guys use any special tools like hose clamps or anything? Thanks in advance!
