AutoGas fueling tips and tricks

I've seen a couple of hangar fires caused by de-fueling.
The common denominator was plastic funnels and cans.
Metal woudl be strongly advised.

I used to carry 5 gal jugs in the car and then used a pump to transfer
to the plane. However, that was back when I could buy FAA legal mogas.
Today the cans sit in my garage.

Ditto here...an old section of carpet as a pad over the wing, and squareish gas cans, allowed me to put the can on the
pad, put my thumb over the spigot, and then tip the can over and place the spigot in the fuel neck, then pull my thumb
away. Pop the air vent plug and let the can drain. Never any problem, until all the so-called gasoline around here
turned out to be contaminated with alcohol...

I though metal containers contribute to static discharge hazards.

It is the other way around.

Electrostatics greatly simplified:

In general it is easier to get a static charge on an insulator than
it is a conductor, i.e. metal.

In general it is easier to remove a static charge from a conductor
than it is an insulator because the charge on a conductor is uniform
over its suface while it can be localized on an insulator.

Holding a conductive can in one hand and touching the metal of the
airframe with the other will bring the airframe and can to the same
potential.

Gas cans are supposed to be conductive.

Plastic funnels are almost never conductive and the act of pouring
stuff through a plastic funnel can generate a static charge.

Use approved gas cans, or at least metal cans, and metal funnels.

Make sure everything, you, the can, and the funnel, has made contact
with airframe metal before opening anything.
