I'm not sure if this has been mentioned, the plastic has carbon in it.
http://www.ultralightnews.ca/ultralightstore/mrfunnel.htm
1. Carbon powder is injected into the Mr. Funnel plastic so that Mr.
Funnel will conduct static electricity (not applicable to colored F1Cs).
Grounding is an important safety feature. Always ground Mr. Funnel by Smart
Tech.

I've fueled from plastic cans many many times (hi-wing Cessna), in
Canada & when on floats. Never had a problem, thankfully. Only thing
I do, if I can, is hold spout closed with a fingertip until it's in
the tank neck and in contact. Mainly to avoid spilling. 'Cans' are
apparently non-conducting plastic, marked "UL Classified" Some are
'approved by the LAFD'.>>>>
>>>>>>>>>>>>>>>>>>>
Don't know if it makes any difference or not..... I have been told that
when transferring gas from a plastic container,,,, if you can keep the gas
from traveling through open air,,, the static buildup will be less....
Therefore I have glued a long clear plastic hose to the end of the spout on
my plastic tank.... by putting the end of the clear plastic hose into the
bottom of the receiving tank, the gas does not pass through the air,,, also
while pouring I grab the bare aluminum of the plane with my left hand while
holding the plastic can on my right shoulder and holding it with my right
hand... this is in an attempt to keep the tank and plane at somewhat the
same electrical potential. The fuel tank in the plane is grounded to the
frame.

| Subject: | Carb Balance / Sync |
Hi all,
Had a nice gentleman come over form Silver City to get a carb sync. He had about
200hrs. on his 912uls. He said he thought it was running ok. Bottom line is
his carbs were not only out of mechanical sync because of uneven cable set, but
the pneumatic sync was out 4" of vacumm.
Moral of this story: it doesn't have to feel or sound bad.
carbs do get out of sync and if you have never synced them, then they are out of
sync. period. This makes one side work against the other at different rpms.
There is no arguement here it's just a fact.
A manual sync is not a fix or a replacement and they need to be pneumatically synced,
the engine needs both. Everyone I know that does their sync evey 100 hrs.
always finds the sync out some. Some more than others.
This is so easy to do I have a hard time figuring out why some are so resistant
to do this required function.
I have yet to hook up a set of gages and find the carbs in perfect sync after some
amount of run time on any 912.
The carb system is a linked system with different components and any one of those
can and do change from time to time.
I would be happy to talk anyone through this if they would like to learn.

Would be interested to see if the carbon-including plastic in a Mr.
Funnel is conductive . Can anyone with a funnel and a VOM check this?
The rubber in today's tires contains carbon and is conducting. Long
ago gas-station people would sometimes get a shock from a car that's
just driven in . All tank-trucks had a grounding chain trailing on
the ground . Not needed nowadays.
Grounding never hurts. How many of you carry a fire-extinguisher in
your aircraft?
When flames start is NO time to go looking for one.

Happened to a friend of mine who flies a rotary powered RV-6. I can send
you his email account of what happened, if you like. He stopped the fire
with the same techniques mentioned by others: cap the fuel tank on the
plane & put out the fire in the gas can with an extinguisher.
He won't use auto fuel any more; fuels only from avgas pumps now.
On the other hand, millions of people fuel boats, cars, lawnmowers,
planes, etc from plastic cans every day with no problems.
About a dozen people had car wrecks within 20 miles of each one of us
today. Anyone plan to stop driving? :-)

One thing that has not been mentioned in the dialog about static sparks is
that one of the conditions for this to happen is a low humidity day. The
drier the surrounding air, the more support for the generation of a spark from
the storage point,namely the nonconductive plastic. That is where the charge is
stored...or on your clothing or some other nonconducting medium. When the
humidity is higher, the charge can be siphoned off or conducted off into the air
better thereby eliminating the charge in the first place. My recommendation
is to be MORE careful during dry days, as that is when the likelyhood of a
spark is greatest. Touching (not rubbing) with your hand all plastic surfaces
will also minimize the possibility of a spark.

Now that makes a whole lot of sense, causing grounding of the Mr Funnel to
be HIGHLY EFFECTIVE as it will now CONDUCT electricity instead of only
storing it like uncarbonized plastic..... such as our 5 and 6 gal red plastic
containers. It seems that they too, should be carbonized.........why aren't they?
Of course this would make Grounding HIGHLY EFFECTIVE instead of possibly
effective.
