Demothen, as others have suggested, I'd make sure you're actually seeing rust as the primary problem. The yeast/bacterial flocculant/crud issue is statistically more likely to be causative, as these guys will accelerate any rust.

Additionally, along the way - as happened in my case - this crap can just about shut down fuel flow to the engine. Filters alone didn't cut it. Ultimately, pulled the tank, degreased/scrubbed it, and replaced the screen and both lines into it. Replaced the fuel lines while I was in there just for good measure. The tank itself wasn't significantly damaged by rust.

Was messy and time-consuming, but otherwise not a terrible job. And made a big difference in terms of fuel delivery.
