I've never pulled a tank, but if I could I would take the tank out and then you can use whatever cleaner you desire and not hurt anything. You would also be able to make sure it's completely clean before you put it back in operation. I know that may be a lot of work, but it's the best way. I would also flush the lines and replace the filter. If you really want it to run the way it should, it may even need to get the injectors repaired. Someone put a link on here of a place that specializes in that. It will probably run if you did something short of that, but it will run the best if you clean everything. You just don't know where all that sticky stuff went to but it had to make it all the way to the injectors or the car would have never run. How much it messed up the injectors is the real question.
