Draining fuel from GX390

A complete newbie question. I have a generator with a Honda GX390 engine.
I would like to drain fuel from it. The manual page says I have to remove the drain bolt and gasket, and the sediment cup and O-ring.

I managed to identify the drain bolt (last picture, red arrow). I opened it and drained whatever fuel came out into a gas can. Now what about sediment cup? Could you please help me find it. Do I need to remove it like the manual says? The picture in the manual looks a bit different from the engine I have.
Thanks.Name:  out.jpg

The sediment cup is directly underneath the fuel on/off lever if equipped.

Thanks. This engine has an in-line fuel shutoff (second picture center), and the manual mentions something about an in-line fuel filter. Would that mean that sediment cup might not be there at all, and it is sufficient to use the drain screw to drain the fuel? Thanks for the help.

I'd say so. All the hondas I have seen with the sediment cup had it located right next to the carburetor under the shutoff valve (incorporated into that valve assembly). If it doesn't have it, I'd say there is no cup and just drain the bowl as you did.
