Secondary Port Vacuum Pump

[Rob]

For those of you that would like to see the inside of a secondary port vacuum pump, I added these photos to the July/August Wrench and Socket column:

Thanks Rob, I've said it before and I will say it again, you are the man.

Well....I try. Honestly, what I'm trying to do is dispell some of the myth and inaccuracy that surrounds the ZR-1. Most owners don't know to check their vacuum pumps for normal operation or know that the seals that seal the top cap to the pump can leak over time when exposed to water. At least now, you can see what happens inside and see how the pump works.
