WOw, I have a 5cfm of about the same pump that runs great and has zero vacuum, guess I need to check the coupler because it doesn't make any sound as if the pump is even turning. Great, thanks.

Hey Mark, thanks for bringing this to everyone's attention. I just did your modification to my pump - works great. BTW, have you had any other problems or issues with this pump? I recently just got mine, there doesn't seem to be a lot of info floating around regarding these MC 90067 pumps.

Happy to help. Pump works great with mod. Ultimate vacuum 15 Microns or better. Take care.
