First of all, we have to differentiate the questions and complains a bit. The B-52 is the Fun line thing, but these are the 707 forums. If one would constantly struggle with the Fuel on the B-52, I would recommend going with "unlimited fuel", set up in the FSX realism dialog.
When we're talking about the 707, we are talking about the detailed systems there, since this is not a "Fun" product, therefore some reading of the manuals and understanding can be assumed to have taken place. Since these are the forums, questions are always welcome and you'll find people like Mark explaining them as good and as often as they can. Thumbsup there.
The 707 runs seven tanks, Center, Left/Right Main (=2&3), Left/Right (=1&4) and Left/Right Tip (="Reserve"). Fill them up with the outer tanks first and empty them from the inner ones then, regarding the special role of the "Reserve" ones.
A more detailed description is included in the manuals, giving you the switch and valve setting.
So if you look up your current fuel distribution in the "IF" column, you will see how to set up those valves and switches and also, you can read what to do next when some fuel has been used.
The very last "IF" item is Main tanks 2&3 equal tanks 1&4 + their Reserve, so this will be the last point were you can (and should) set up the fuel distribution on the plane.
Running all four engines at the same setting, this will give you all four tanks (1,2,3,4) going to "0" at the very same time. I don't know if the real plane flew like this, but I can tell that the manuals for the CS state it and it works just fine there.
If you look in that diagram, your flight should have ended before this "0" point. Otherwise, it will be ended then. ;D
Fuel dumping is more or less an emergency procedure but, as this is a sim, you can simulate it every time you want to of course. This thing also requires some management and it will mainly be the same as if you would burn the fuel at a very fast rate.
Only Mark drops his fuel all at once. ;D (still laughing, Mate, don't get me wrong though. By the way, isn't their a Lake named after you then?)
Since this Boeing only can crossfeed and not crosstransfer, the only thing to prevent you from running dry is to set the valves in the right way. But, as you see, all four tanks are supposed to run down at the same rate on the later part of the flight, so they all "feed" your engines and they all should have the same amount of fuel when enabled this way of feeding.
Your description doesn't reflect this setup (which comes from the manuals). So you may want to improve the setup there to eventually enjoy the 707. :)

So, currently, you are missing the step when Main tanks 2&3 equal tanks 1&4 + their Reserve. Look it up in the diagram and fly safe(r).

| The center tank will empty first..no problems here I just turn the pumps off and everything is fine. Then the outer tanks go down, but when I turn the pumps off right before they go empty, they still drain down and the engine die's. |
