The 30-40' rise might be a big problem. To do it right, you would want to pump up that distance plus 2%, then be able to maintain the 2% slope without sags all of the way to the sugarhouse.
I have seen it done, but it required a series of utility poles, an expense that 60-70 taps couldn't justify. For your case I think draining back to a common tank makes more sense. Also, run your 3/16 all the way to that tank, every foot of drop in elevation is more vacuum. If entering a mainline for gravity flow, all vacuum ends as each lateral enters the mainline.
After draining back you will have sap setting in the tank, , leave it (to mellow?) or haul it back.
The cost of just the first pole would be more than all of the year's sap will be worth.
You are between the proverbial rock and a hard spot!
Dave Klish, I recently bought a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
