Drain the tank.
Remove the sending unit.
Pull the tank out.
Put about a four foot long chain in it.
Shake it all around.
You do the hokey pokey...
Rinse it out and shake some more until it's clean.
To keep it from rusting you can buy a kit from POR 15 or others to chemically treat and coat the inside of your tank.

Put a lot of solvent in the tank with the chain.

how long do you wait to let the por 15 dry/set before re installing the fuel tank?What kind of solvent did you use?How about gasoline as a solvent or alchohol?

You would have to read the POR15 directions to see how long it takes before you can use it.
I use gasoline as solvent but it is a bit dangerous. You can make a lot of ignitable fumes in a short amount of time.
