Note that regardless of what you do, a container of fuel (without its own oxidizer) would never successfully light/sustain fire without first having displaced the majority of the fuel with atmospheric air to provide the necessary oxidizer. That’s why you can’t light a full container even with tracer rounds. Otherwise, you are only be able to light the part of the fuel that leaked into the atmosphere.
