vacuum plugs?

[jdog78]

Does anyone know the size of the vacuum plug needed for the m90? I am talking about the plug at the back of the supercharger. Mine fell apart

Call up Roush to get another one. I think they were a buck.

either 3/8 or 5/8..
i think it's 3/8

You can probably buy them at your local parts place for less than the shipping charge from Roush.

3/8 was the correct size. Thanks for the help.
