Since my motor is out for rebuild I've been researching this very topic. My '67 only had the tank sock filter, and with a fresh motor I was wanting a bit of an upgrade.

I picked up a Robb Mc mechanical fuel pump and he recommends a high flow filter if it is between the tank and pump and a regular filter from pump to carb.

Here is the info from the instructions -

"Fuel Filters: A filter between the tank and the pump is not required if the factory in-tank filter sock is still in use. If the in-tank filter sock has been removed (which is a good idea in most cases), a large, free flowing (90 to 200 micron) filter such as RobbMc PN 1024 or 1025 should be used. One or more additional filters (30 to 50 micron) should be used between the pump and the carb(s). "
