Good question, a blockage in the fpr will negatively affect fuel pressure (high) so the screen is there to not circulate any crap out of the fuel rail (rust, corrosion) when fuel is returned back to the tank, its meant to be cleaned when a blockage is suspected (otherwise it would be a sealed unit, replace when blocked).
"Fuel pressure regulator failure due to contamination from accumulated fuel rail debris causing excessive fuel pressure." (from AFI diagnostics)
With you removing that gauze, your fuel pump filter is also now your fpr filter too lol!
