Your tank has a definite sump area.
The sediment should flush to that area simply by adding/filling and emptying with the drain several times.
If the sediment is caked to the bottom of the tank, then you are going to have to remove the tank to allow access via the filler neck with a broom handle or stick of some sort.
On that unit, removing the tank is about an hours worth of work.
That is robbery!
