Huh?

1.  As far as I can see there isn't a floating fuel pickup in my tank,
so the stuff at the bottom is what gets used.

2.  The "garbage" is what the fuel filters are for.

3.  Water (in those quantites :-) is harmless.

4.  If there's that much crud in the gas tank it should be drained an
cleaned.

5.  Every time you add gas the tank gets stirred up, any crud is gonna
find the supply inlet no matter where it is.

6.  I frequently run down to the last tenth or two of a gallon (yikes!)
and haven't seen any problems ever.  Engine runs the same with full tank
or empty.

7.  A tank mounted, gasoline cooled, fuel pump is the only reason I can
see for not using the last couple of gallons of gas.

I could be full of it of course... ymmv
