Terry, I really only use the 6mm clear because it fits the BVM UAT center fitting. Since I am not using the UAT I will definitely be using tygon. I am probably going to make some changes on the Scorpion fuel system and will remove the UAT and replace it with the PST tank as well. The BVM UAT was still collapsing with the new P-160 installed.

It is going to be 50 degrees next weekend, maybe we can go fly...
