The factory setup already has a "surge" setup in the tank...ever look inside the stock tank? Pretty much all cars these days do.

Surge tanks aren't immune to these scenarios either. When you are using enough fuel to support 1000+hp, you will go through more fuel than the surge tank holds. You are still using fuel at a MUCH higher rate than the feed pump, plus....if your feedpump starves...guess what....so does your surge tank.

lol, let me guess you think the feedpump to the surge tank needs to be as big as whats feeding the engine?

I think the application in this scenario is a little different. We're looking at very short periods of starvation and a rather sizable surge tank (in Commanderwiggens case).

I also imagine that as soon as the surge tank goes below 100% full the pump feeding from the gas tank now has little to no pressure and can fill the surge tank quite quickly.

exactly, there is little to no pressure, Its flowing at more volume then the amount of fuel going into the engine, even if the feed pump is much smaller then whats feeding the engine.

That is a largely incorrect statement right there. The stock pump with no restriction (which...there still is...that tank has no VENT to outside air, so there is a restriction even if it is just filled with air and not fuel), won't flow as much fuel as a 1000hp engine will consume...ESPECIALLY not E85! This isn't my opinion...it is a FACT!

I share one issue with you, my car runs out of fuel very soon AFTER the light goes on and the needle is sitting 1/2" ABOVE the "E" line and the computer says you have 50miles left

Your car has many miles on it on your setup...no need to get paranoid, it woulda blew a long time ago. The filter element can be cleaned it's just a screen.
