All right.  For crying out loud.  Who can know this stuff!  I don't remember 
studying this in my Shakespeare class????  I am forced to conced, to relent now 
that, while literature remains the highest value field of study in the human 
experience, it is perhaps possible that engineering has some small role to 
play....

But gadfrey!  Who could know that 'Jerry' cans are stronger than automotive gas 
tanks?  

Oh.  Dumbledore.  

Literature wins.

A bit different though; 'Jerry' cans are normally fully sealed (and strong 
enough to withstand the pressure from fuel vapor).
Automotive gas tanks are not.  Modern cars are closer to being sealed, but 
older Triumphs are totally open to the air.  

So if you live in an area where dew forms on the grass (and your windshield), 
it also forms in the gas tank.  With non-ethanol gas,
the water runs to the bottom, where it can't evaporate, and causes rust.  (In 
colder climates, it can even freeze, leading to
"frozen" gas lines.)

With ethanol, the water combines with the ethanol.  Once the water 
concentration becomes high enough, both the water and the ethanol
settle out to the bottom of the tank.  What is left might run, but is typically 
lower octane, so causes engine knock (like Andrew
experienced).

FWIW, and as I recall, the US copied the "Jerry can" design from the Germans 
during WWII, hence the nickname ('Jerry' being a
nickname for 'German' at the time).  Far superior to what we came up with 
originally.
