I've been thinking about this today.... You asked what would clean the tank and I think that your problem is just the opposite of what you are thinking.... for years that tank had pure gasoline in it and has managed to get gunked up... now in recent years E-10 has found it's way throughout the country and even into most marina's.... E-10 actually does a pretty good job of breaking up the varnish and gunk in the tank.... I suspect that it is doing just that and thus you are now having issues....
I also was thinking of another option for an in tank screen that wouldn't let the gunk just fall back onto the tank.... An inline fuel filter containing a pleated element with the inlet opened up to about 1/2" would stop the crap from fouling your fuel line but it would trap it so that you would eventually get it out of your tank...
