CorvAircraft> fuel filter?

[corvair-list at steensland.net]

Vairs,

I have both of WWs manuals, and after reading through the 601 install
manual a few times I noticed that there isn't any mention of a fuel filter
in the 601 installation. I was thinking of using the ellison 3a on my
601xl, but based on WWs conversion manual trash from the newly constructed
tanks would possibly clog the carb.

Any thoughts as to where the filter would go on a 601xl install?
