Oil pressure sending unit

Moto Guzzi V700, V7 Special, Ambassador, 850 GT, 850 GT California, Eldorado, and 850 California Police models

The Italian company Facet manufactures the oil pressure sending units used on all Moto Guzzi Big Twins since 1967. I do not know if they have always been the manufacturer, but I believe them to be the current manufacturer. Here is the vital data specific to this switch:

Facet part number 7.0033
Threads: 12 mm × 1.5 mm
Tip diameter: 4 mm
The latest replacements require a 21 mm wrench. Earlier versions required a 22 mm wrench.
The pressure that activates (grounds / earths) the switch is 0.25 BAR (3.6 PSI).

Similar oil pressure sending units (same threads, different activation pressure and wire connector) from Facet include the following:
