|
|
I'm back home and catching up on email and Kolb stuff and saw my name mentioned.
St. Gobain, the mfr of Tygon tells me that their Tygon F4040 formula
yellow translucent line is designed specifically for gasoline and
other petroleum products and is compatible with E10. It is rated down
to -35 degrees F and up to 165 degrees F. Not recommended for enclosed
cowl engines due to the hot environment often encountered therein, but
good for locations that don't get that hot.
On the Rotax List, there is a discussion of this topic and one lister
said that he was not happy with this line but I'm not sure he is using
F4040A. Perhaps he is using another Tygon, of which there are many
formulations. He is testing another formulation now. Check the Rotax
List for more on this.

There are many formulations of tubing sold under the Tygon brand name, but
the F4040 "fuel and lubricant tubing" is the only one they recommend for
fuel containing ethanol. It is, I believe, the only Tygon brand tubing
with the yellow color. There is also at least one other manufacturer
making a yellow "fuel tubing", but my experience is that the other brand
(at least the other brand sold by McMaster) is inferior.
I still prefer the blue Bing line.

Brother Hague:
Had an interesting experience with the blue Bing down here... In service, it became the Brown Bing... and in some instances, the Black Bing with a brown furry side dish after about 5 months on the job. The puzzling aspect of the situation was that the clear Tygon fuel line pieces installed in the same system for the same period of time yellowed a little, but remained clean and unaffected inside. They were still soft and flexible. The attached photo shows the strange deterioration of the blue line, along with samples of the new blue stuff from the same batch of the corrupted Bing line and another batch of blue line obtained from another source.
I have no idea what caused this. I use only Amoco Premium gas and PZ air cooled oil. I changed out the lines with clear Tygon and have had no recurrence of this problem
Worth what ye paid fer it...

Interesting. The blue line that was on my Ultrastar when I bought it
looked like that, but I don't know how old it was. OTOH I have some blue
line on one of my PPG's and several years later it looks and feels just
like new.
I wonder if it's not chemical, but UV damage that does the clear tubing in?
