Post by: Kim Mortimore on July 26, 2012, 07:52:29 PM

Does anybody know where to buy tubing flexible enough to use inside clunk tanks?  Thanks.

Kim, i am currently using the small blue tinted silicone tubing in my small 2 or 3 oz. tanks. In the bigger tanks the normal size will work fine.  I believe it is Dubro. I have tried neoprene, small latex and surgical tubing and they have all either split or bent forward in the tank upon landing. The tubing seems to flex and work better than you would think, not having to slide all the way to the extreme sides, tops and bottoms to pick up fuel. The small tubing is somewhat hard to get onto the fittings, but i find if i take my time it will work.

Sullivan medium silicone in the white package seems to work best for me.  It is more flexible than most.  With other brands seems like the clunk movement is more inhibited.
