So I'll give some more details of my sugar bush. I currently have 230 taps on 9 different 3/16" lines that see an 80' drop in elevation. I can get 28" of natural vacuum on my top trees. I have close to 100 more trees at the bottom of our sugar bush I'd like to tap that are below my current collection tanks. Unfortunately, the land there flattens out and I can possibly get 20' of elevation change over 600-700 feet. The area where my collection tanks now is tough to get to once things muddy up. If I can tie in the extra 100 below it all tied in somehow, it gets me close to the road which will make collecting much easier. This is why I am thinking of this pump set-up. For me it's two-fold:
1. Be able to include the close to 100 additional taps
2. Be able to pump my current lines the additional 600 or so feet closer to the road.

I don't have power down there so the whole solar powered 12V pump appeals to me. Maybe there's a completely better way to approach this?
