Oversized fuel tanks question

All,

So I see bikes like DR650's with Safari fuel tanks, so I'm wondering; how do they work? A good 30% of the fuel is below where the fuel hose would normally be, and the lowest parts of the tank are (what looks like) below or even with where a fuel line would go into the carb. So how do you get access to that last bit of fuel?

How is a fluid moved higher than pickup? Usually with a pump..or, in this case, a fuel pump.

In the case of both my MXC and 640E the very last bit in the right side is had by laying the bike down on the left side. In practice when riding offroad most of it sloshes over. But there is a little get home gas that stays on the wrong side. Those are both KTM tanks. But the Clarke tanks on both my XT350 and XL600R were the same way.

That said, none of mine have ever had a fuel tap lower than the carb inlet. My KTM petcocks are both about level with the carb inlet. But it doesn't seem to matter.

In some cases, you don't normally access that little bit of fuel.

Some of the larger tanks have fuel pumps.

For my KLR, if I really need that extra bit (its like a reserve reserve) I can tilt that bike to one side and the gas will slosh over and I can get a few more miles.

Not wanting to hyjack hanshotfirst thread here.
But this question seemed semi relative.
Wih the big asserbis 20litre tanks etc discribed, would it not be better to cary fuel in jerry cans rather than the big tank or some sort of tank top tank that could at least be moved when empty, i have never riden a bike with one of these tanks on but they look unbalanced visualy at least, jery cans lower down look a better option to the unanitiated in these matters.
What do the experienced say on this subject .
