I put it in the channel, as in Photo 1 (ie not directly against the flange). It just seemed to me that an O-ring (that, if cut, would be circular on cross section) should fit into a channel and not up against a flange. (It's not a flat gasket after all.)
Anyway, fired it up and no leaks seen so far.
On a related matter: How many people actually use a torque wrench to achieve "25 Nm/19 ft-lbs" on the filter housing? As long as you don't strip threads, is it possible to over tighten it??
BTW, Fray, you're right: lousy pics. (Had I been running around with my camera specifically seeking out stuff to shoot, I'da thought of hittin' the Macro. For some reason yesterday I didn't.)
