1972 911 thermo time switch

[rowingone]

I have a 1972 911T MFI that is leaking at the thermotime switch. Does this sensor have a gasket o ring or washer installed with it?

Yes. Flat copper ring.

Yes, the thermotime switch on your 1972 911T MFI typically uses an O-ring to seal it and prevent leaks. If it's leaking, it's likely that the O-ring has degraded or was not properly seated.
