Small transfer pump

I am looking for a pump that would pump 50 gallons from my garage to
my second floor tank which is about 100' feet away from the garage.

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.
