You can also see if there's water in the fuel. There used to be such a filter mounted on top of the pump but repep pumps don't have that.

I have abandoned mechanical pumps altogether because of quality problems and now have a filter at the inlet to the electric pump and a glass bowl filter at the carb inlet.

Also be aware that the Zenith 228 came with a multiple-disc filter at the fuel inlet so be sure to clean that before you start it up. Zeniths were good carbs. Some had adjustable main jets. Mine does.
