Using K&S Sta-Flex Fuel Line.

I noticed after a tank of my gas/glow mix that the fuel line is hardening... should be fine for the fuel lines,
but I'm worried about flexibility in the line from the clunk to the stopper.

What fuel line have you guys used for your gas/glow engines?

Thanks in advance.

Fuel line for gas and nitro are two different animals. You can't run gasoline in silicone , alcohol is not compatible with some plastics.Its not advisable to run alcohol fuel in PVC type of tubing.

I use the TYGON brand yellow fuel line it works great and it keeps flexible, but make sure its TYGON because there is a similar yellowline and this one tends to harden

Aeronut,

Thanks ... I'll find some today!

Stihl has a very flexible fuel line for in tank use.

The Tygon tubing that I have used gets half hard. My airplanes are not very pretty.

How would neoprene fuel line work? http://www2.towerhobbies.com/cgi-bin...&I=LXD735&P=RF This one has a seam but there is a seamless line available.

Neoprene seems to harden more than Tygon but both are ok for gasoline.

I find with our gasoline the neoprene stays flexible longer than Tygon. No idea how it will work with gas and glow mixture.

Well put...good man....Best Regards...Catp,n

Neoprene will have trouble with alky , even the 10-15% added to pump gas will affect it.

I was to a auto store (Advanced Auto) and they had a section for small engines parts. They had 1/8 inside dia clear fuel line for chain saws. it looked very good....I guess I will try it. $1.99 for 2 feet. Capt,n
