Abstract. Yields of sugar maple sap collected from three plastic pipeline systems by gravity, vacuum pump, and a vacuum pump with a transfer tank were compared during 2 years in northern Vermont.The transfer system yielded 27 percent more sap one year and 17 percent more the next year.Higher vacuum levels at the tapholes were observed in the transfer system.he transfer system yielded 27 percent more sap one year and 17 percent more the next year. Higher vacuum levels at the tapholes were observed in the transfer system.
1 Maple sap is a slightly sweet, colorless liquid. 2  It takes approximately 40 gallons of maple sap to make 1 gallon of maple syrup. 3  A gallon of standard maple syrup weighs 11 pounds and has a sugar content of 66 percent. 4  Maple syrup is the first farm crop to be harvested in Michigan each year.
