I checked the fuel line where it connects to the Carb, and there is 'no filter' in that connection. Engine is Mercruiser 4.3LX
Not the 190hp 3bbl Carb version
Mine has a 4bbl Carb, creating 220hpBD

The four barrel carb actually has a small "inline" filter AT the
Junction between the carb and the steel fuel line. The BIG nut that attaches the fuel line to the carb has a
Small filter hidden inside it. Carefully remove the nut and the filter should pop out. It has a spring behind it.
In the
Clymer Mercruiser Manual it looks like a small "Cartridge" type filter.

You can get a Clymer Manual at West Marine. (Recommended)

NB
PS: Using HEET or DRYGAS at this time will NOT be of any benefit.
