G'Day Eric,
Here are the "under bonnet" pics of my snorkel installation.
I rotated the cannister 90 degree's then formed a pipe that connects to it. The pipe has a water drain at the bottom (near the oil filter) and a bayonet mount at the other end.
The "bayonet mount" on the pipe just sits inside the engine cover (it is located by a stainless steel strap that you can see in the first photo) and the flexible pipe that connects to the snorkel unit itself has the corresponding bayonet fitting.
Obviously I had to drill a hole in the cover in the appropriate position.
You can see the bayonet fitting in place in the second photo, but I have left the engine cover off.
Normally you fit the engine cover, then align the flexible pipe bayonet fitting, in the hole and rotate the handle about 60 degrees.
I'd have to say I think Russ's option is a simpler design, but in an M model you don't have metal "behind" the wire grill, so where his snorkel is mounted is effectively vinyl, and I personally didn't want to cut that vinyl/fabric top, so I opted for the solution you see here.
I've had the snorkel in place for 3 or 4 years now without any problems.
