I"ve got mine mounted on the lower firewall, I don't know when I'll change it, probably about the 100 hour mark, and will also cut it apart for inspection. You should see a pressure drop when it starts clogging at higher throttle settings. The filter element is rather large, so I would guess that it would take quite a bit of debris to clog it. I have a cowl access door on the right side of my engine cowl, it allows me to sump the fuel filter, check the alternator/water pump belt, and check the oil sight glass on preflight. It is as easy as replacing an oil filter when it needs changing. 
  
If you have a gascolator, I would think that this would replace both the gascolator and fuel filter.

 I have the same type of filter, mounted below the mid-fuselage fuel tank.  I had to run a length of tube to the rear of the airplane to mount a sump.  These filters are designed to work on fueling systems (ie, on the hose that you'd fill your tank with).  They are meant to flow a LOT of fuel, and to catch a LOT of trash and water.
