Doesnt anyone sell replacement parts for heater controls? Dealer said controls have been discontinued. Mine are leaking badly so nothing works. The lines are fine and I am getting good vacume but controls are leaking. Wondering if someone sells the whole setup new, or if someone sells the two round vacume tree things. I would pickup a used one, but would probably end up with something just like what I have.

Remove the vacuum control and disassemble it. Clean all the old, dried sealant from the two halves and the rubber seal rings, and apply some fresh silicone grease, then reassemble. It shuold last another 10-15 years.
