I have worked on numerous aircraft (pistons/turboprops/turbines- large, small, military) that have filters after pumps and before the FCU fuel control unit (carbs/throttle bodies/fuel injection systems). There is no reason a filter cannot be installed after the gascolator. It needs to be properly shielded from heat or blast cooled, just as your gascolator should be. Several manufacturer's of fuel control units recommend a filter of a certain micron size before fuel enters their unit. Having a serviceable filter forward of the firewall and not in the cabin area is a good idea. These filters are sometimes referred to as "last chance" filters that remove the smallest of particles that could clog one of the metering ports before entering the FCU. If the filter is after a pump (ie boost) the filter used should be rated to handle the psi from the pump. Think of it this way: Finger strainer- big chunks, gascolator- small chunks, final filter "last chance"- tiny chunks, then into the engine driven pump or FCU. Some models even have a filter on the fuel inlet to the FCU from the engine driven pump. PS.All of these filters need to be on a regular inspection schedule so they can be checked for debris.
