Can't say what's best, but mine has never failed me in 36+ years. I have the filter pictured above mounted under the cab, so it's before the fuel pump. And the Q-jet has a small filter in the fuel inlet.

If your carb has no built-in filter, it might be a good idea to add one after the fuel pump. But as mentioned, it's generally a bad idea to put one above the engine near the carb. How about placing it directly after the fuel pump? It would be a little harder to get to but might be safer.
