Hi Jos
Glad to hear you are home and in good spirits! Best wishes on your
recovery, keep giving everyone hell!
"From a good source i learned that mogas or avgas, spayed, sprikled or
throw at/on hot surfaces will not ignite."
Your source is not good, but in fact very bad.
See:

It is true that oil has a lower auto-ignition temperature than 100LL, but
get fuel to 500 degrees F and it will auto-ignite! Get Evans to 700F and
it too will auto-ignite. The exhaust can reach auto-ignition temperature
for oil, fuel and coolant.
You can't plan for all trauma that may happen in a aircraft, but IMHO it
is bad practice to use aluminium fittings firewall forward. Brass is
better, SS or steel better yet. Aluminium has more of a chance of failing
and be the cause.
