It doesnt sound as if youve done any damage to the pumps and the pressure drop across your filter sounds normal although I wouldnt wait until it reaches 15 inches of mercury before changing the elements. The initial fuel pressure from the tank to the engine bay is pretty low less than 20psi.

Becuase injector presure are extremly high 10000 psi the fuel gets filtered down to 2-5 microns. Regarding filters for a carbureted application a 100-micron inlet filter is still a good idea while the pressure side filter does not have to be quite so fine so a 40 micron filter with a large surface area would be the best. With your mechanical pump and pre-pump 100 micron I would use a 10-40 micron to the carb.

The 10-micron size seems to be the go-to or universal size on just about all brands. Carbed engines mostly were 20 micron and 10 fuel injected. Todays ethanol based fuel we now use 10 micron on both ford eec4 systems have been running 5 micron.

Fuel system pre-filter before the pump. What I am confused about is the micron size rating. Barry Grant even sells fuel filters that filter down to 8 microns.
