First of thanks .... now On my home made atty there is no cart. The fluid get pumped up, from the bottom of the atty housing, to wet the Silica wraped coil. Any excess goes right back down to the bottle. The bottle itself is the pump, since it is a sealed system it will not leak and the bottle last me up to a week before I have to refill. The one thing I have found is that I have had to drop my nic intake using this atty and that itself is a BIG savings, was using 24mg and dropped to 12mg.
Sorry got off track... example if you take a bottle, say Windex, open the nozzle and squeeze the bottle, not the trigger, the fluid in side will spray out. This is the same function. The liquid inside will be pushed up the tube, that goes to the bottom of the bottle, and into your cart. Just find the correct size tubing that will fit your usage, amount needed to your cart and that's it.
I hope this helps you
Carlos
