So it's just as simple as 1.opening 2.changing 3. closinging?
Hmm. Well, kind of. For those of us back yard (garage, DIY, etc) mechanics - the fuel filter swap is like childs play.
If I can remember right, I used two open end wrenches and a socket for the top bolt and another socket for the two bolts that secure the filter in its housing. Damn, my memory is not all there - this early in the morning.
It twas an easy job. If you can change your own oil, then you can change out your fuel filter. (provided you have the tools)
Just be sure to run the vehicle and inspect for leakage before taking her out on the beltway! There are torque specs - but they are quite low, like 14 or 19 lbs. At work at don't have my HELM manual.
