I am sure you guys are tired of my updates & whinging about my problems/needs but it seems like the little #90 didn't liked to be polished - the heater blanket opened up.  Hard to believe it even worked, it more or less was in bits when I took the tank off.  I even think someone worked on it before because there is a solder blob in the middle of it.  I suppose now I can polish all around the tank ha!

So now for a solution for a heater for it - when I worked on my brother's Jenson I ended up with an extra heater blanket.  He is sending that extra one (which is brand new) to me to see if I can get it to fit and not electrocute me.

In other news, I think I am going to try to fix the sight glass seals, though I am trying to hunt a proper O-ring. There is another #90 thread where a suggestion was made but no follow up if they worked.  I found these on granger, O-Ring: 5 mm Nominal Inside Dia., 7 mm Nominal Outside Dia., 7 mm Actual Outside Dia., Black, 25 PK

Hi Jeff,

I like to use o-rings also, rather than tubing (unless the OD is too large for the nut ID, of course.)

Have you considered a metric o-ring? A 5mm ID x 7mm OD x 1mm wide might work. You would need around 9/32" dia. clearance inside the compression nut. I have a bunch of them, and could send you a few, if you think it's worth a try.

and this interesting idea:

  Have you considered Teflon tape twisted into a thin string and then wrapped
around the glass tubing (as much as seems needed)?  It works the same way
as a slice of silicone tubing.  I can testify to that!
