Scrubbing the gas tank

Probably not It has a bladder in it kind of like a well tank or a pressure control water tank with a bladder It's very similar You can't replace the fuel pump or the sending unit generally when the tank is fubar it gets replaced New ones are expensive 16, 1800. ones out of other cars are well questionable at Best. So cleaning is probably not an option trying to find a tank out of a matrix or a Yaris or a vibe or something like that seems like it may be a much better thing I don't know I haven't had time to fool with it yet I'm sure I'm going to see soon.

 

When was the last time this car ran?

No, you cannot "scrub" the inside of the fuel tank. A US-spec Gen2 Prius has a fuel bladder inside a sealed tank assembly.

If you have old (stale) gas then the best you can do is to pump it out. You need to disconnect the pressure line -under the car, or at the fuel rail. Then hook some kind of hose to the fuel line. Jumper power to the pump or use a capable scantool to activate the pump. If the pump works then collect the discharged fuel and safely dispose of it.

(It is really difficult to get a hose or tube down the filler to reach the bladder).
