?When to Pull the Tank?

[cristeven]

Can i get any guidance on when to pull and clean the gas tank? Seems like a lot of work without too much to gain. But, the engine and transmission are already out and i'm trying to get everything done while there's extra room.

What are the benefits of cleaning the tank? Doesn't the filter already do the job? (not trying to argue, just trying to learn) I've attached some images of my tank (i think)

thanks,
steve
