I calculated it as a 45 psi drop using this calculator

What is the inside diameter of the coil? Total vertical head? (IE: pump is on a shelf 2' off the ground, highest point of the coil or hose is 6' = 4')

Hmm.. I run 50' of 1/2" copper with a Chugger in my "linear" cfc. No problems at all. I suspect at 100' it would still work... but I only have like 4' head on it total...

Assuming half inch true ID all the way, not accounting for any elbows, you are looking at about 13.5' of friction loss at only two GPM. Then if we assume 4' of static head you are already deadheading the pump if this is the unit you have: http://s3.amazonaws.com/PWAY01/chugger/Chugger-Pump-CPSS-CPPS-Manual.pdf
So you might wind up getting a gallon or so a minute out of it. Really need something that outputs more pressure.
Edit: or larger tubing.

You'd get around 2 GPM in that scenario.
