I am looking for a very flexable tubing for uniflow in 4 oz plastic R/C tank.  I want  something more flexable than today's average fuel line, even more flexable than the classic Prather fuel line (Yes, I understand there are two types of plastic tanks; the ones that are leaking & the ones that will leak)  The plastic tanks many years ago came with a VERY  flexable tubing that had to be changed at least yearly.  The clunk moved around very freely.  I am willing to change the tubing if needed.

Contact Yaro at www.aerohobby.ca . He has a very soft flexible silicone line that we use for F2D shut offs . I've used it for clunk lines and other things that require soft line .
