Default Gas Engine Fuel Line

What's the best gas engine fuel line you have used? I want one that stays flexible over the LONG term. I have a Sig 4*40 and I'm considering that new OS GGT10 as a drop-in. If I switch, I know that I'll have to pull the tank and change the lines. The way I have it set up, pulling the tank is a bit of a pain in the ass and I don't want to have to pull the tank each flying season to change the lines. I have tried the K&S stayflex in my other planes and it does not stay flexible for very long. The Tygon doesn't seem much better. If anyone has experience with a different brand of fuel line that has worked well, any tips would be appreciated. Better yet, does anyone know of a soft, flexible GLOW fuel line that holds up to gasoline?

THANKS!!

Viton is the most preferred gas line over Tygon as it stays much more flexible over time. There are a number of places to order it. McMaster Carr is one.

I sell some of the best gas line. The gas line has proven to be just as flexible as glow fuel line and just as viable as Viton over more than 5 years and counting but at a fraction of the cost. Shoot me an email direct to my address.

Sullivan Products 10' ProFlex Large Universal Fuel Line: 3/16" Tubing | Tower Hobbies a little on the pricey side, but worth it.

Be sure you change the stopper in the tank to a gas stopper also. You can buy just the stopper.
