There's a foam 'doughnut' between the two, I presume i'm fastening

parts are in contact?

just watch there are foam doughnuts and there are foam doughnuts
trial and error as to what type works for you.....

Yes, if you have to change the doughnut you really need a selection. I
had to cut one I bought on ebay down to size. The original no longer
worked properly after I took the cistern off to change the siphon.



Lie wise. The one supplied with the syphon had to be cut, as indeed the
original had been.
