    Put some diesel fuel in it and drive around town on the trailer. Let it sit a few days and do it again. Then drain it out. You'll be surprised how well it works at cleaning.

    not sure what kind of junk you have in the tanks but my tanks had bad gas that had turned to varnish when I bought it. I used a couple of gallons of Acetone and 10 steel ball bearings per tank and towed the boat around for a few miles. I then pumped the tanks dry with an electric fuel pump and pulled the ball bearings out with a magnet, got the tanks real clean.
    For good measure, I also installed a fuel water separator from West Marine-

    and never had an issue.

    Go get a cheap drain snake, cut it so its about 10" longer than the distance from your filler to the back of the tanks, attach to drill, stick drain snake in tank, press button on drill. That'll break it up...now ya just gotta figure out how to get it out. Shop Vacs don't do so hot with gas soaked sediment...tend to turn into flaming shop vacs.

    Ever blow the lid off one?
    Those little clips don't hold very well under sudden pressure.

    Since it looks like you have a lot of gunk, try fuel polishing. You can rent the systems. Do a Google search on it. Some friends have done this on their tanks with good results.

    Remove the tank if you can and have it steamed cleaned and pressure tested while its out .

    Nitromethane is an extremely powerful industrial solvent too, kinda pricey cleaner, unless you could find some contaminated fuel someone was gonna dispose of anyway....
