Pumpguard 36200 is a strainer

You would expect to find a filter/strainer on the suction of any diaphragm type pump. It protects the pump valves from debris.

The Johnson F3B pumps are I beleive flexible vane pumps, although no reason why they should not also be protected, just not as important as it is with a diaphrgam pump.

You'd not expect a filter or strainer on the discharge side of a pump. The above are not suitable for fitting on the discahrge side anyway

It's a coarse filter protecting the pump, and should be undone and cleaned out every time you join or leave the boat, perhaps once every dozen showers or so. If you have only just found it, expect a lot of gunk!
