I would agree that most of the "junk" settles to the very bottom of the tank, and most engine
supply outlets are a bit above the bottom of the tank to allow room for "junk" to accumulate below. But if you have an installed fuel polishing system then running it for awhile after you finish a passage
might help keep the level of the "junk" below the pick-up.
Most all of the fuel tanks I have dealt with have inspection
plates or some sort of removable cover on the top of the tank. For serious fuel polishing removing that plate and working a long probe around the accessible areas of the bottom of the tank is about as good as can be done.
Considering that my diesel
fuel fill hose snakes 15 feet before getting to a 90° elbow
fitting at the top of the tank - anything flexible enough to allow it to follow the hose would probably not be rigid enough to get to the bottom of the tank from that elbow
which is at the top of the tank.
