WTB: Lycoming IO 360 CHT sending unt

[Steve Dawson]

The original CHT sending unit for M20J IO-360 isn't working and I'd like to find a working one for replacement. Does anyone know what the cost and where to get a new one or have a used one for sale?

It's available from spruce. It's a Rochester 3080-38.  120$.  I just bought this.  Use a very thin ignition wrench to back up the stud when you tighten the nut.  If not, it torques the stud loose and ruins the sender, that's what happened to me.

Thanks Byron.
