What is It ??

[Garyd]

I need help with the following :
What is it- Pipe coming off the bottom of the radiator reservoir ( but not connected to it). It is wired. think its mounted in the wrong place. Where is the pipe supposed to end.

Bottom pics :
Pipe coming from underneath air filter goes to some sort of gismo and then.... ends ubruptly.. ???

Is this an accelarator choke system. Seems like the two should meet at some point.

That looks like a pressure switch to me, happy to be wrong, No idea where it would go

The one under the radiator reservoir looks like a pressure switch. Maybe a coolant level switch operated by the weight of the water in the reservoir.

Middle pic looks like a vacuum control solenoid on the left and the unit under the air filter a vacuum operated diaphragm.

Bottom ones an idle up solenoid for a/c
It increases idle speed when you turn on a/c
Not sure what the top pic is
