Can someone identify this part: - The 1947 - Present Chevrolet & GMC Truck Message Board Network

It's on the left hand side next to radiator. Has a vac. line going to it but it's not connected to anything. No wires to it either. Sorry for the crappy cell phone pics. Thanks

Looks like an aftermarket cruise control module

I thought it was part of a cruise control but there is nothing else to go with it. It has a knob on it that turns but has no tension and looks like there is an adjuster screw with a jam nut on the other side.
Thanks for the reply.

I do believe it is a vacuum driven air compressor which was used in the AC Delco "pleasure lift" air shock system

Thanks for the responses guys. I am going to remove it and see if I can find a part number on it then do a search and see what happens.

That was a factory option vacum pump that would pump up air shocks off the motor vacuum. I have mine installed on the 71.
Here is a link for it. Has all the info you need.

Wow! Thanks Andy.
Odd thing is I only have that piece and the air shocks and they are junk. The SPID doesn't show that as an option either. Beginning to wonder what my truck really is!!

I'm not sure if they where for trucks. I know for the cars they where. I have mine off now and use the gauge for the air bags out back. I modified the gauge and put a momentary switch on it to run the air compressor. I have the vacuum pump in a box in the garage.

Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
