I think you are forgetting about the excess heat in the return fuel
Tom.
You don't want it right at the intake of the pump as the fuel supply
could
get hotter and the pump vapor lock. Also for vapor lock reasons one
would
like to have the pump buried in the fuel tank.

PLEASE DON'T  "T" the return line.   More than one pilot has died to
prove
the error of this practice.  I think the most recent fatality was in an
S51
Mustang here in Florida a few months ago.  Paul correctly identified one
good reason not to do this.  We could spend a lot of time discussing all
the
reasons this is bad practice.

Paul, thank you and Tracy Crook for setting me straight. I was looking for
the "kiss" fix, but it looks I only got half of it. The "simple and stupid"
half. Thanks again.

Your welcome Tom. That's why we are here.
