OK, 10 minutes. I don't remember ever seeing pictures or a straight-forward procedure for this.
I've looked for "fuel filter" in the Bentley manual before, but found not much, if anything, about it.
I would appreciate it, as probably many other A8/S8 owners here, if someone can either point to pics or a procedure for entry-level mechanics among us (yes, that includes me).
Thanks in advance!

Text procedure.
Pull the fuel pump fuse.
Lift the right rear corner.
Just forward of the wheel well, underneath the car, pull the plastic cover, revealing the filter.
Remove fuel filter with open end or (preferred) flare nut wrenches. There are two banjo bolts that connect to banjo fittings on the inlet and outlet fuel lines, that attach to each end of the filter.
Replace fuel filter, using a new copper washer on each side of the banjo fitting.
Replace fuse. Test.
Replace cover.
Lower car.
Oh, and don't be smoking a cigarette when you do this, and try not to drop any steel tools such that they spark on the concrete. Have a fire extinguisher handy, especially if you are clumsy. ;-)
That's from memory, from about a year ago, but I think it'll do. I'm sure I'll get corrections if not.

Thanks. I can --imagine-- now how to do this but I am visually oriented: pictures anybody? If I...
...can do it with this procedure and addtional pics, I'll write a complete procedure for audipages as I did for spark plugs replacement and instaling a Schroth harness.
