Do I tap into the fuel line before the mechanical fuel pump or between the fuel pump and the carburetor.  Also what is the preferred way to hook it in the system.  It is a 6v pump with max 4 psi pressure, as prescribed.  Electrical is not my problem but I do want it to work properly without causing flow or air problems for the engine.  Thanks as always.  Charlie

Gene,
A filter goes before the AND after the pump. The one before filters larger debris, to protect the pump while minimizing flow loss into the pump.  That one is often like a very fine screen.  The one after filters out smaller particulates that can cause problems in the carburetor.
