any 'taste' from the tubing??? and thanks for the info...
For the syringe type mod I use 5/16" X 7/16" vinyl tubing from a farm supply or hardware store . You can cut it to any length you want and it fit's on a carto snug (no leaking) but can be easily removed for dry burn or torching . Drip tips also fit this tubing just right and it only cost $0.30 per FT.
