SNIP

It is mounted very low so that the selected main drains
to it by gravity, per plans.  The bottom half inch or so
is in the airstream of the big belly naca inlet, so it gets
good cooling.  But steel is a poor conductor if heat.

Tracy is correct, I should have given more detail, my
system may be a problem for someone if they buried
the tank in the cowling somewhere with poor or no
cooling.

Perry,

Carbon steel is a pretty good conductor of heat.  Stainless
is a much poorer conductor.  Your exposed surface is
an excellent idea for cooling the sump.
