siphoning water
(OP)
is it possible to siphon water uphill by placing a 40 gallon tank (air tight)on a higher place between inlet and outlet.pipe from the inlet is connected at the top and pipe to the outlet connected at the base? is this workable?

What would you be doing, if you knew that you could not fail? Ans. Gov lobbyist.

To go up hill - they generally use a pump.
Now - there is a "pump" used on farms for many years that used flowing water to move a portion of that water up hill. Had some kind of "hammer" cylinder in it - I think. Don't remember name or type of pump - but still used. Not very powerful - but over a day's time - could move a rather large amount of water. And didn't require electricity or gas and didn't need to be monitored - run all day or all week w/o a problem.

This is a ridiculous concept and it will not work. The outlet of a siphon has to be lower than the source, you can't siphon water from the ocean, then drop it above.
Adding the 40 gallon tank just turns it into a shaggy dog story. The 40 gallon tank is just a wide spot in the line and irrelevant to operation of the siphon.
For the siphon to continue to operate, gravity must have a larger effect on the outlet. If it takes more force to lift water up than to pull water down than the outlet is too high
Because of friction and other energy lossed, all water lifting devices such as water wheels still need an excess of energy above the amount of energy that is necessary to lift the water.

A sketch may help us understand.
Good luck,

First link I came across: http://www.instructables.com/id/Worlds-greenest-water-pump/
Requires constant water flow so not applicable unless you have a stream/river.

RE: siphoning water
This is not about water head in the tank. The tank will function as a conduit not as a reservoir.
Mr Siphon seems to think that merely connecting to a tank at the bottom or top will cause the flow to reverse:
"pipe from the inlet is connected at the top [of the tank] and pipe to the outlet connected at the base [of the tank]"
Imagine that you have a siphon (including the tank) completely filled with water and valved at both ends. What happens when open both valves at the same time?
In all siphons, water always flows downhill.
Mr Siphon wants one to flow uphill.

If you are trying to siphon the well over the hill, the answer is no. Your sketch shows the water well being at a lower elevation than the outlet gate valve. This also assumes that the well water does not have pressure (artesian well).
If you filled the entire system and then opened both valves, water will siphon into the well. The siphon will continue until air enters from the tank bottom connection and breaks the siphon effect. At that point, the tank contents will then drain to the outlet.
The system drains to the well because the water pressure at the outlet gate valve is less than the water pressure in the well by the difference in elevation. The tank elevation is not important, it is the pressures in the piping at the outlet connections.
This is why civil engineers construct tanks on elevated ground. The lower the elevation is away from the tank, the greater the water pressure.
The weight of water will always cause the water to flow downward. Water always flows to the lowest elevation.
