Fumes of unburned gasoline are hazardous to your health. Yes, they can
adversely affect you. There are known cancer causing chemicals in gasoline
which is a longer term risk. Suffocation, collapse, death are the shorter
term
risks.

Exhaust fumes carry similar risks. If you have exhaust leaks that enter the
van, they could kill you. If your exhaust is intact and is not leaking and
your
catalytic converter is working properly, the fumes should not enter the
vehicle
to any great degree and some of the most dangerous components should have
been deactivated.

It is nothing to fool around with.
