Title: Tygon fuel line?
Post by: frank mccune on January 14, 2015, 06:38:20 AM

     Hi All:

     Is this line suitable for glow fuel use?  Is it suitable for Diesel use?

                                                                         Tia,

It is really not glow suitable but is diesel/gas friendly.

It is meant for petroleum based fuels.  I have used it with glow fuel and it hardens up some (it is pretty hard to begin with compared to silicone).  It was installed over a year ago and it still is fine, although I really flew on it a couple months.

Frank,

It's perfect for diesel use.

It's available in a wide range of sizes, so be sure you use one appropriate for your intended use. I use a very small thin walled size which works perfectly with TR shutoffs.

I get mine from the local mower shop, as it's used on whipper-snippers (maybe brushcutters in the US).

  I think silicone is a lot better for glow fuel, its much more flexible and resist heat better. I used Tygon in my Lotus Esprit and it was OK for that, but it gets stiff over time. Then it cracks and dumps raw gasoline on the coil and distributor.

I use it in most of my ignition planes as I run fuel most of the time but also run gasoline or Coleman stove fuel part of the time. I have not had much trouble unless I remove it after a year or so as it gets very stiff and hard to put back on the fittings at the tank and spray bar.

Real Tygon brand Tygon works perfectly well in my whipper snipper where it's immersed in fuel for the fuel line.

Maybe inferior brands will harden and split over time.

These guy must be using yellow vinyl, I've had tygon on my Foxberg for years with no problems.
