The previous owner of my 1991 f250 460 did the emissions delete on the truck. My question is about the pink vacuum line. I found it broke off and unplugged. Is this OK? Should I plug it.
Thank you for all the replies. All advice helps and is appreciated.

A picture of specifically what you are referring to as well as the vacuum diagram on the hood will be helpful here.

If you google your calibration code found in the drivers door jam you will likely find a vacuum diagram if yours is missing.

The vacuum line to the fuel pressure regulator MUST be hooked up.
The vacuum line to the MAP sensor MUST be hooked up.
