Fluid transfer low flow to high without a pump

It appears that you have placed part of the question in the thread title and part into the message.

Possibly you mean to ask about a situation where there is ethanol in an 8000 gallon truck. A hose is run upward to the top of a larger tank with a capacity of 80,000 gallons. Contrary to expectation, when a valve on the truck is opened, some ethanol comes out of the hose end, though the flow eventually stops.

One can posit an explanation for this involving a poorly ventilated tank on the truck.

The 80,000 gallon tank is underground?
