Gascolator
Unfortunately, or fortunately depending on your point of view, we as Canadians do not have to option of not installing a Gascolator as it is a required component of the fuel system in any Canadian registered aircraft.
The gascolator is an inline fuel filter, much like the one Van's show on their plans, with the added benefit of being serviceable during annual inspections. I don't believe takes away from the operational integrity of the fuel system in any way.
My two cents worth!
