Perhaps we can agree that the main thing people should do is buy stuff that will last.

I may just be stubborn, but I will keep my old VFD's and other stuff running as long as possible. In fact I am replacing the alternator in my 1986 Volkswagen Jetta diesel car today. I'm welding up a new bracket so it will hold a standard alternator.

To recap.

1. Less than 10 HP and no tank = CSV (Cycle stop valve)

2. Intermittent variable loads (like in a house) = large tank.

3. High HP, Variable load (lift), and/or displacement pumps = VFD (variable frequency Drive)

4. Future = unknown, but it will be better with more choices.

47 Willys and a 63 International tractor, still in use. Welded a few brackets myself. Don’t get me wrong though, I like new gadgets too. For instance my new cell phone is not even a fancy one, and it’s still amazing.

To Recap

1. Less than 10 HP and no tank = CSV (Cycle stop valve) DISAGREE
more like;

1. Less than 200 HP with a pressure tank. = CSV AGREE

2. Intermittent variable loads (like in a house) = large tank. AGREE

3. High HP, Variable load (lift), and/or displacement pumps = VFD AGREE

4. Future = unknown, but it will be better with more choices. AGREE


Seriously enjoyed the thread Bill. Hope the alternator bracket goes better than my last throttle cable bracket for the Willys!
