Tubing for feeder mod, what size?

[foretwoone]

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?

16 gauge stainless steel tubing is what i use.

Stainless might not work great for a pump feeder Java...but maybe mostly stainless with a small piece for the flex at the pump head. If your in a real pinch foretwoon, one of those grill lighters with the long neck can be cannabalized for the small dia. tubing. If you want some in quantity, try Mcmaster - carr. I think ( not sure I would have to look it up ) it is 3mm OD 2mm ID ?

Actually it works really well as long as your bottle is directly centered with your connector. One piece from the atomizer to inside the bottle. Drill a hole in the top cap and dropper on the bottle put a o ring on the tube in between the cap and dropper. When you tighten the cap on the bottle you have a nice leak proof connection. Once in the bottle you can use a short piece of flexible tubing to make squeezing easier. But thats just how i do it there are a ton of different ways people have theirs hooked up( a lot of it depends on what kinda case your going to be slapping it into ). Really the only wrong way is if it leaks all over your electronics.

Java, could i bother you for a picture? Normally i'm good at putting this stuff together in my head but if you have a working setup i'd love to be able to see it.

Maybe I should have clarified. For my top feeders I use a pump top bottle similar to the Dripper from Notcigs. For a squeeze type bottle...yea, no problem with stainless there.

rockproof, how do you get the tube through the top of the pump bottle? Do i need to drill a hole in the pump part, and do i need to block the original spray hole? I know i saw a mod a while back where someone had the bottom of the bottle sticking out of a box and they just pushed up to spray a few drops into the atty. Cant seem to find the thread anymore though.

I don't come through the top (although you can and if you did probably go the route you guessed). I come right out of the side (where the original hole was) by just expanding the hole size with a drill bit and super gluing in the tube. See pic attached of my 14500 copper mod with the feeder backpacked (the eGo is shown for scale).

Ah, ok, thats exactly how the madvapes juicebox is setup. I'll take a look on McMaster for some of that 3mm tubing.

I use This pump (the top 10ml bottle) with a 1 inch piece of this tubing shoved in the outlet hole and epoxied to the bottle and this tubing which extends to my mouthpiece out of the box mod.

Trust me this works. One pump to the tottle bottle will produce 2 drops. For one drop you can reduce the bottle pump stroke with some jb weld or epoxy or just make a half pump stroke.

You can also use a modded pressure fitting (hobby store) to attach the tubing to the cart; instead of using glue. It makes replacing the cart really easy

Sorry about that my Dyslexia musta kicked in. For some odd reason i thought you were asking about a bottom feeder.
