REFLECTOR: EZ poxy & ethanol

[Alex Balic]

I had a similar problem as Chris- although I did not put any mogas in my
mains, I had my sump filled with 89 pump gas for engine testing, and after
about 6 months, I noticed gas weeping from the bottom- so I  pulled it and
the Jeffco had become soft and pasty- not sure what happened there, I
re-built the sump using a new batch of Jeffco, but have been running on
100ll since just to make sure there is no problem... I will try the auto
fuel again at some point.

Peter,

 

You are not the first to warn people about EZ poxy and ethanol and I doubt
that you will be the last.  I refer you to Al Gietzens' email where he has 6
years experiences with ethanol containing fuel in his EZ poxy tanks without
a problem.  I personally tested a strip sealed in a container with denatured
alcohol with no apparent effect after 6 months. Despite all the warnings, I
have never seen or herd of any documented evidence that would indicate that
EZ poxy is adversely affected by ethanol containing fuel.  If you have a
reference, please share it with the group.

Mark, 

That almost certainly sounds like the EZ poxy that ships with the kit and
NOT Jeffco (the really good stuff).  

 

My understanding is that the EZ poxy holds up just fine with aviation fuel
but I'd be VERY hesitant to use it in conjunction with fuel containing
ethanol.

 

I may have missed, but are you flying an auto conversion?

 

Peter

I don't know what was used. I didn't build it and I'm not that familiar with
fiberglass. 

 

EZ-poxy is the epoxy system that Velocity sent with the kits; and is most
likely what was used.  Shine a light in the tank - should be a
yellow/brown/gold color if EZ-poxy, gray if Jeffco.
