Re: X Air Hawk fuel tank 'shedding' particles into fuel
|
My light yellow tanks started blistering so I took them out fabricated aluminum tanks and solve my problem.

Not everyone has a Jabiru engine fitted,?? The Rotax prefers car
fuel.
Either way, the fuel tank in the X-Air aircraft is just vinyl ester
resins and they are affected eventually by fuels of any description,
especially when you have to make it as light and thin as possible.
Best for any fuel still seems to be polyethylene but its heavy.... ?
Look at how many outboard motor fuel tanks there are around the
world that are left outside day and night, in some and rain and use
all sorts of fuels and yet they are still working after 30 years,
can't do that with a Fiberglass fuel tank.

Wouldn’t it be safest just to use only 100 all fuel only, after
you have thoroughly cleaned your tank? ??
Mogas has to be carefully sampled every time to ensure No
ethanol, which is the problem for fibreglass tanks. ??
While 100 LL can lead to plug fouling if proper mixture
management is not employed, ?I never had that problem even with
my Jabiru engine that had no manual mixture control. ?The Jabiru
engine manual even recommends using ?100 LL for good engine
performance and cooling. ? My AME highly recommends using AVgas.

throw in Mogas and take off. ?The STC requires specific sampling
technique prior to a flight for compliance. ? The “devil is in
the details “. ??

Very interesting and valuable information,
as usual Michael.
I will keep my eye out.
I noticed my gascolator valve leaking today.
My tank has been completely dry for 3
months. I just put fresh fuel in it and I thought to open
the gascolator. Sure enough, it started leaking. Now I
understand what those white rabbit like hair particles
were.
I did notice these particles in the fuel
filter before but now I will clean it more often.
Many thanks!
It honestly depends on the fuel and the additives that
are used locally when it is produced.....?? Fuel is not
fuel any more..........
I have seen some excessive fuel tanks deteriorate in as
little as 12 months from ethanol car fuel. If you have
debris inside the fuel tank that is flaking off the best
thing to do is drain the fuel tanks, put about 3 feet of
chain in the fuel tank and Shake like crazy !?? the chain
will break off any of the exposed fibres, you then need to
flush the fuel tank as many times as you can to remove the
debris and you should be good for another year or two.
Because the debris is normally fibreglass it is almost
impossible to see in the fuel filter when it is wet
Because it is completely translucent (just like Glass)??
When it dries out however it looks white like rabbit fur
or something similar so if you just looking your fuel
Filter if it has a glass Shield you may not see that your
fuel filter is 90% clogged. It is amazing when you pull
the fuel filter apart and the fuel starts to evaporate it
looks like all of these fibres are actually growing on the
fuel filter as they dry out and become visible.

My XAir tank was whitish, I
only used 100 LL , and I never had any debris issues
in the Gascolator.?

Hello everyone,
I have read that the x air Hanuman comes with two
different types/colours of fuel tanks - one that
is capable of running avgas and MoGas with ethanol
(yellow-ish tan coloured tank), while the other
white-clear tank only accepts avgas. Please
correct me if I'm wrong.???? I have not heard this ???
Anyway, I have the yellow-tan tank that can accept
both grades if fuel. I don't know if the above
information is irrelevant, but after 150hrs of
fuel tank use (14yrs since new), I am noticing
flakes from the material of the fuel tank.
The only fuel that has been run in this plane is
100LL.?
I notice the fuel filter trapping these particles
but why is this happening ?????
The resin is leaching
(being eaten) away by the fuel additives from
the fibreglass and the fibres are breaking off,
this is your "debris" most probaby
?
