John,
I always install when possible the filter / water separator before the pump and at the lowest point possible. On my CZ I used Perma-Cool metal fuel filter / water separator with a drain below tank level and it works very well. Replaced the petcock with aircraft type drain. the thread is the same. Take look at it:

It has large capacity and will capture larger pieces and almost a qt of water before it fills up.

> Looking at the pictures of fuel filter, pump installations, the filter is after the pump.  In auto installations the pump in tank has a screened inlet and then filter someplace between the pump and the injection system.  The plane has a gascolator and do I place the pump next like auto installations, then into the filter like the auto installations, or why not.  JohnD
