Why not just leave the bubbles be?

As long as the bubbles are not forming from air leaking into the
siphon, I would nto worry about it.

Why did you think the old siphon was not sanitary? The trick is to
fill the siphon up with metabisulfite solution, put it into the carboy
and start the siphon let the sulfite drain into a waste container,
when the siphon is full of wine stop and transfer it over to the clean
carboy.

I'm trying to make things a bit more sanitary in my winemaking process, so I
bought myself an auto-siphon. A 3/8" I.D. hose fits over the pipe coming
out of the auto-siphon, a little loose for my taste, but a 5/16" I.D. hose
will not fit.

So, my issue is this: when in use, it seems like a lot of air stays in the
hose and I can see bubbles all along the length.

The solution I've tried so far is to just have a very short length of 3/8"
hose at the end of the auto-siphon, with a long length of 5/16" hose crammed
into the other end. When it works, it seems to drastically reduce the
bubble problem, but I do seem to have trouble keeping it going.

Any suggestions?
