i am the exact opposite.I have also found that the "cheap, Chinese" fuel line keeps it's elasticity much longer than the genuine Tygon fuel tubing. I still only use Viton for the clunk line, but everything else is the Chinese stuff.
The blue line from Taildragger is the Chinese line I mentioned.i am the exact opposite.
weird, but i feel great with the genuine tygon.
i also like taildragger's blue line stuff whatever that is.
The blue stuff is working great. Once it is on you pretty much have to cut it off so it's not good for fuel dot use.
Did your tank get excited or sumthin[emoji1]
