I realized I had the vacuum delay valve hooked up backwards in the previous video I posted, so I redid the video. The delay valve is supposed to delay turning on the vacuum switch. The blue side of the vacuum delay valve faces toward the vacuum switch. Here's the new video.

The orientation of the vacuum delay valve can be seen in this thread:
