Got me thinking though.  What about the idea of sticking about 12 neodymium (rare earth) magnets on the underside of the fuel tank?  Spread around.  The idea is that the inevitable rust particles that form will get attracted and stuck to the areas where the magnets are.  You wouldn't even have to epoxy them on or anything; they are very very strong.  So, instead of all these rust particles naturally flowing to the outlet, they are stuck at the 12 points.  Could buy a lot of time, decades even.

Back in 85 when my Vanagon was built, magnets such as these were indeed "rare".  Nowadays, they are readily available.
What do you think?
