The fuel and air in the cans heating up build pressure inside the cans.
And that is while not even leaving the ground.
I dare not imagine what a 8.000 ft density altitude would add to that pressure.
No fuel in cans in my airplane, thank you.
With respect, some misconceptions in the above post.
I routinely ship gasoline, crude oil, naphtha etc etc samples by air world wide. There are certain (IATA) regulations with regard to packing and dangerous good declarations that have to be followed, but its nothing onerous. Jerry cans would be fine provided they were further packed into crates in accordance with the regs.
Indeed, typical sample cans used for gasoline are far less robust than jerry cans, so I would have no concerns regarding pressures etc. Particularly the case for Avgas, which is a low vapour pressure fuel in any event (if it wasn't it would rapidly vaporise at altitude)
Incidentally, "venting the cans at intervals" would have no affect on reducing pressure other then momentarily - the fuel will quickly regain equilibrium pressure (which is based upon a liquid's vapour pressure and temperature) once re-sealed.
