And this

Is it out of a bronco? I would say emissions like the Can Purge Solenoid.

[broncomatt]

Electroncily activated vacume solinoid. Hard to say what it controls, most purge valves in the 70's were temp controled (in the thermistat housing). The closer you get to the end of the 70's there were many added emssion vavles. Check your rig for a vacume diagram or give exact year of the engine and it can be looked up.

It's a friend's '72 rig. Never saw anything like it on my '71.

[broncosbybart]

my guess is that the engine probably came out of a later model donor vehicle. i have never seen either of those soleniods on an EB engine. A 72 would have been pre-emissions, like your 71 is.

[jdowns67]

That's what I thought but the motor is definitely out of the '72. It only had 28K miles on it when the guy got it.
