1972 911T MFI pump question

[Dourobot59]

Hi folks,
I am working on a 1972 911T and the car's service records/history are not complete.
Previous owner is unsure of all the history.
I am wondering if the yellow paint on the MFI pump screw heads was applied at the factory when the car was built or has it been added by a shop that did some work on the pump?
Thanks for the help with my rookie questions!

That paint is typical for the screws on the MFI pumps. It looks too new to be 50 years old, so chances are your pump was serviced or rebuilt at some point. Note also what appears to be gold paint on the barometric cell (that cylindrical thing screwed into the top of your pump), which would not be a factory finish - also suggesting at least some cosmetic work on the pump at some point.

I had my pump serviced last year at MFI Werks, and the yellow paint was reapplied to all the screws.

The term "eyewash" comes to mind...... but indeed it is a clue that the pump has had some attention since the car was built.

Note also the heating tubes for the warm up thermostat don't seem to be connected so if you're trying to get that car running properly, that would help.

There is no heat tube attached to the outlet of the warm up thermostat. Only to the inlet, which isn’t visible in the above pic.
