I have seen different sizes of those screens. Better take a look at this page:

And that doesn't include ancient versions like these:

The best gascolator is Steve's Gascolator. ACS has them or you can buy direct from Steve's.

I've installed a couple of them. Really nice units, easy to service. But buy extra o-rings when you order it; they're metric and not so readily available.
Now, after finding that the gascolator has no screen, your A&P needs to pull the filter screen out of the carb's fuel inlet (or the fuel injection servo's inlet) and clean it out. Debris that should have been stopped by the gascolator will have continued on into the carb or servo.
