I use a syringe with 16 and 18 gauge needles to fill my carts. Get them at least 1.5 inches. That will reach down in most juice bottles. The syringes also come in handy for mixing your own juice (use the bigger needles because raw juice and VG are thick). The Barrels have scale marked by mili liter.
