Here is the mystery.  

  

 This is a brand new airplane.  AMD-manufacturerd CH601XL with all new everything and 20 hours on the Hobbs.  It has never been fed anything other than blue 100LL.  The fuel samples from each wing tank are always blue and have never shown any water or strange stuff.  But, the fuel samples from the Gasloator are always unmistakably Yellow.  Oh, and the engine always roars sweetly.   

  

 Does anyone know definitively what's going on?  My theory is that the brass/copper alloy gasolator, being new, is giving some color to the fuel sitting in it.  (Yes, as I'm writing this I realize that I should check the sample color right after flying... thus the value of public confession.   Although... I have pulled as many as 5 sample tubes of fuel from the Gasolator during pre-flight and they were all yellow.)   

  

 Has anyone else experienced the yellow tinge?

the yellow may be water collecting in the gascolator.  the engine will run because the screen will not allow the water to go to the engine.  the little doohiccy is doing its job.

Someone's probably peeing in your gascolator. The  good news is apparently the engine loves it.

  

 Sorry, I couldn't resist,

The fuel pulled from my gasolator was discolored for awhile after

I started flying 633Z. I didn't note when the yellow to dark yellow color

went away, I haven't seen it for 1++ years. I attributed the color to

leaching of the rubber fuel lines. Easy to test - put some fuel in a new

line, plug the ends, and check for color in a week or two.

If you don't have rubber lines check for other sources that could leach.

I had the same problem after using the fuel line supplied by Zenith in my  701 I bought in October of 2003.  I ended up replacing all the Zenith  supplied fuel line with fuel line purchased at Auto Zone and have had no further  problems with tinted (yellow) colored fuel.

 I informed Zenith about the problem, returned the problem fuel line and  they credited me the amount I paid for the new fuel line.

 The tinting occurred with both Avgas & auto gas.

 Hope this helps.
