In addition, the car is equipped with a dealer installed 14.9 gallon second tank which is connected to the main fuel line through a simple tee, and it has no screen. So essentially there has been no tank screen in the car since it was new.

When I began using biodiesel a few years ago, I went through a period of frequent filter changes, and some pretty impressively clogged primaries, but never a clogged line. Now my tanks are completely free of gunk. While there is some risk in running without the screen, it is not a great risk. In my view, a fuel line blockage is no more work to remedy than that required to clear a plugged screen.
