Sight Gauge Tubing

[Dick B in KY]

What are you using for sight gauge tubing? My Tygon tubing has become cloudy and discolored to the point of being hard to read. My fuel is 93 octane auto fuel ( non ethanol), up to this point.

ive replaced mine with more tygon c-210-a . this has lasted a several years , has changed a little but still good . ill will replace it when it gets bad again . i use only non alc gas . there is probably a better tubing out there , i don't know what it is .

Dick,

Chuck hints at an issue with "Tygon"...the name is simply a brand name; and there are many, many versions of tygon - literally hundreds.....the stuff is primarily used in laboratory applications and it is made in many types - resistant to specific chemicals, pressure, temperatures, etc. Some of it is reinforced.

I simply ordered new stuff from Kitfox when it yellowed out - I figure it will simply get replaced every few years - not very expensive in any case.

I got stuff from a local small engine repair shop. Yellow on one tank and blue on the other just to see which is easier to read. So far yellow wins out! I use "marked" non-ethanol off road (boat) premium fuel.

Anybody know the tubing size off the top of their head? I need to replace mine (again) but that info is up at the hangar.

checked my notes and I'm using tygothane c-2101a 1/4 in. ID. this stuff still gets discolored. every few years I replace the tubing when I do the condition check.
