You need to calculate:
The total horizontal run;
The total height difference;
The number of bends.

The height difference is measured from the bottom of the tank in the
basement, to the top of the tank on the second floor. With this you
can calculate the resistance the pump will have to work against. This
is called "head" and is expressed in terms of vertical feet. The
diameter of the pipe matters.

As this is going to your second floor you are probably looking at a
larger pump. (ie not a little 120 gal/hour power head) And a larger
pump still if you want to use that very small diameter hose. This is
deffinately doable, and probably worth you time.

With 100 feet of linear travel, about 20 feet of vertical head, and a lot of
backpressure from small diameter tubing, I can't see a pump that can
overcome the head, and at the same time not burst the hoses.
My strong recommendation would be to give real consideration to one of the
commercial water exchange hoses such as the Python. It can be hooked to the
in house taps, are long enough to avoid the outside trips, use house water
pressure to move the water, and are adjustable enough for your requirements.
Once the old water is siphoned away, add some water conditioner and turn on
the tap.

You probably want one of those electric water pumps used to drive an RO unit
when the suplly pressure is too low. They produce around 90psi and cost
about $200. They are designed I think for that little bitty tubing and also
are designed to run for a long long time. Look at a RO supply place or
catalog. I see them all the time.
