Is this a vacuum test port?

[roveroverme]

Saw this weird hose connection and I don't remember it from my other M1028. Is this a test connector that should be blocked off or does it connect to something on the engine?

A picture would help.

That is the hook up for the vacuum regulator valve for transmission modulator.

Where is the normal location where it connects to?

 

[dependable]

The valve is mounted to passenger side of IP.

Is it called a cdrv? I don't have one, I think
Where can I find it?

The CDRV is the tuna can shaped item on the passenger side of the engine.

The Throttle Vacuum Valve is on the side of the injector pump and controls the shifting of the transmission.

If its broken you don't need it just connect the hoses to the vac valve on the ip....finding a new one is almost impossible

It's not broken, it's not there at all

Thanks yeah I figured it out (thanks to warthog), the tuna can is there. But I am missing the vacuum valve for the tranny. Can you help with a part?

Show us a picture of the passenger side of the injection pump.

I found it after Warthogs post. He had a link of another thread of his encounter with vacuum issues.
looked it up in the TM , then. I have to get used to the TM more, Right now it's just a large collection of info for me, once I know a bit more how to navigate through it and know where to find what in it I'll use it more. At this moment I would spend two weeks of reading and won't get anything done on the truck.
