Im starting another box mod, but this time im doing a V.V top feeder. Just finished getting a regulator from TI and i ordered some part from madvapes. Only thing i cant figure out is what size tubing to use for the feeder. I'd like to use a pump bottle and make it similar to the one madvapes offers at 3.7v, but mine would include two 14500's with a manual trimmer to make it variable.
Any ideas where i can get tubing that will fit into the head of the pump bottle?
