Like, the T and a little header/sump with huge pumps behind and below the rear seats?
Where acceleration and gravity meet and pull everything there? :)))

Better check your seat too - see Ray Wards account of high-powered take-offs! :))

While learning in a Super Cub I discovered that fuel will not run up hill. So, while doing stalls in climbing turns, just as it snapped into an inverted spin, my pencils went out the door and the engine quit. It shouldn't have, but it did.

 

The (Thank God aerobatic instructor pilot) just yelled his usual "what are you going to do now". I was looking through the plastic roof at New Jersey turning slowly above me.

I said we are spinning. He said pull the stick back. I did that, and he said stop the turn.

 

My legs were laying on the bottom of the fuel tank. I got a heel on the wrong pedal and pushed it to the stop. New Jersey never turned faster, as the engine came back on at full throttle.

 

He pulled off the power and said he had it, and the Cub came upright with a rush of air going every which way through the door and windows. 

 

A month later, for my next lesson, I had the tail up and was about to lift off, when it swallowed

a valve and locked up with the prop up and down. He said what will you do now?

 

 I stayed on the ground (grass) locked the brakes, slid down a long hill and into a wire fence. No further damage.

 

I couldn't let go of the stick.  He just laughed some more. So, then I learned about landing a Colt on a hot day with two lard asses on board.

 

In my Lola race car, I had 4 pumps because the cells were long and had pickups at each end. They all fed a single sump tank (little propane bottle) mounted high in front of the engine.

 

The bottom of that little tank fed the engine. An overflow with a restrictor, went to the right cell, so it was always full, and the left tank would run out first, because the ATL fast fill port was on the left tank. A vent connected both tanks to an ATL discriminator valve.(Lets air in or out but not fuel). It never starved for fuel and it would draw every last drop of fuel for winter storage.
