You might buy some of this extrusion and make a sump tank out of it.
It will dissipate any heat that is in the fuel when the fuel is
recirculated to the sump tank. The neat thing about the sump tank on
the back of the firewall  is you can see that you have fuel
with a clear plastic sight tube on the instrument panel.
When it starts to go down you know you are in real trouble :)
One peice of this on the floor of the sump tank should be enough.

Perry Mick is probably building an oil pan out of this stuff as we speak.

How did you guess? Yes, I've designed an oil pan with fins.
Unfortunately, that 5013 extrusion is not in stock, they would have to
manufacture it. Which means I would have to buy several hundred pounds
of the stuff. So I'm looking at other extrusions or possibly having the
fins made of 1/16" aluminum angles welded on both sides of a 1/8" plate.
A welder I know in the Denver area will weld it up for me. He has been
in the welding business for 25 years. I'm hoping this will reduce my oil
temps, it is better than adding another oil cooler. If it works, my
friend in Denver will produce them for people who want one.

I removed the oil cooler from the plane this morning to tap in all 8 (!)
of those measurement points you want.

Maybe we get get a bunch of orders together and buy a batch.
Anybody else interested in five feet of this stuff. What would several hundred
pounds cost Perry? Anything in stock similar?
