I've seen all the filler cart mods and not had much luck with them. I don't know if anyone has thought of this before, but works really well for me. I've found that after about 5 topoffs the filler where you drip to refill gets compacted and matted up and won't absorb the juice any more. When this happens I get a few good hits then need to refill. When I take the cart off to refill it, I only get like 2 drops and it pools up.
I have found that if i take a straight pin and poke holes through the length of the filler. It kind of aerates the filler and reopens the fibers a bit more. This causes the juice to soak in way better and deeper into the filler. I have also after doing this and filling it up, I then repoke the filler again and it even soaks in more. Then I top off with a few more drps till its just about to pool solid on the surface. So far this seems to work really good.
I hope this helps on ur carts also, let me know how it works for ya.
