True007,

You have an older Backdraft, we have always had debris in these tanks. I think if you use a bigger filter as for volume, you wouldn't need to change as often. I never seen the filler tube corrode to the point of clogging up your filters. I have had alot of problems with local fuel stations with debris as well.

My suggestion would be to remove and flush your tank. Check the interior of the tank visually for debris, change your filter and see if it continues.
