[TR] winter storage

[Reihing, Randall S.]

I think the cans I have are exact copies of the German "Jerry" cans. Very strong, never leak, all steel, extremely well sealed, and well made.

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.
