Ok, I get the picture. I thought maybe it had some silly little 5 cent rubber seal or O-ring that needed replaced, but from what I'm reading, it's all got to go. I picked up the part and ready to install it.

Read the threads on runaway diesels. You have to be careful when installing the valve because if done incorrectly, the engine can run away once started.

Did you confirm that the problem actually lies in the shut off valve by testing the valve by itself independent of the rest of the vacuum system?
