The simplest and least expensive option is use any tank full, if extra weight is an issue, use a smaller full tank, most other options that allow you to run from a full tank down to The last drop use internal trap door sumps and cost a few bucks. Whats your intended use?

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

I've autocrossed my Chall T/A since 1975 in the SCCA Solo II events... car is currently nationally prepared to run in class E/Street Prepared (since its class inception ~1986). Although I've always run a mechanical fuel pump, I've never had any fuel starvation problems.. In fact, I've always preferred to run the auto-x events with as little weight as possible... typically starting the event's day with about 1/3 tank of gas... ending up with about 1/8 tank... tank is factory stock. One note -- if you run a Challenger with more than 1/2 tank of gas, or worse with a full tank, you'll not only have all that extra weight (bad!) but the fuel will probably spill out of the side-filler onto the quarter panels unless you have a very good sealing gas cap, and perhaps wrapped with small cloth soak to it up.... The g-force in such events can be pretty high to force the fuel up the filler and beyond the gas cap... from my experience!

it has been my experience that the carb'd motors will not show fuel starvation for brief moments, like going around corners. a cab has two fuel bowls for reserve in that instance where the pickup cannot get the fuel to the pump - EFI has no such " reserve" the second the pump has no pressure, the injectors have no pressure as well - no pressure and they do not supply the engine with fuel - it is more instantaneous then with a carb.

When I sell EFI systems to the "rock crawler" guys they have the same problem, only worse, because they can sit at weird angles for a long time.
So the ultimate solution, that's also fairly inexpensive, is to use a tall narrow intermediate tank. This approach allows you to keep the stock tank since it only used as a reservoir.
One local guy fit the intermediate tank in the front of his trunk. He can now run down to the last drop while sitting at a 45 degree angle.
Same idea as this! http://www.ratdat.com/?p=168

Nice way to make a sump! I run "in tank" on my hotrod but am planning a sump on another project. I will likley use the CO2 tank starting point.

I got the trap doors from Fuel Safe and had the box made out of aluminum. Your setup should work good too with that big filter. I wanted a bigger tank anyway,mine is now 25 gal,and knew an access door with an in tank pump was always the plan so thats why I chose the route I did.

Hotrod City Garage has a interesting aluminum EFI tank. It has a lower sump (1 inch lower) at the bottom front of the tank, a internal perforated 5 inch tall open box surrounding the pickup, and internal front and side baffling. They have a choice of pumps, and a drain plug option. What do you think? Picture 1

Those are nice and are a bolt in option. They were more $$$ than I had available when the time came for my fuel setup.
