I understand the physics of it, but surely the point of putting a filter in the line is to catchg any muck from your tank. The two items that need protcting are your carb and fuel pump, so a filter before the pump is to needed protect it. I guess what is needed is some idea of how restrictive your average fuel filter is and which makes flow the best. I have a filter before and after my Carter electric fuel pump and have never really given any thought to how well a fuel filter flows.
