Dynomite, that (in bold) did it! Holding finger over the end of the nylon vacuum line resulted in the vacuum pump cycling about every 10 seconds - much less often.
The rubber fitting appeared to be very lose, and I zip-tied it to hold the nylon vacuum line tighter, but no change in the 1.5s cycling of the vacuum pump. Must be the aforementioned leaky check valve?
Great pics, BTW!
