Hi Candle,

When held upright, top open parts of glass sediment bowls have a smaller diameter "recessed", glass circular inner surface for the screen to rest on, and immediately adjacent, it has a larger diameter "raised", glass outer circular surface for the gasket to rest on.

After the glass bowl is installed and tightened, the circular gasket should contact the upper, "solid" metal circular surface and the lower, "solid" circular glass surface.

The perforated fuel screen should never become sandwiched between the gasket and either the solid metal above, or the solid glass below, thus allowing very thin fuel to escape.

With CSRS, like with most of us, after becoming confused about "exact" fuel screen placement, just try to remember why nobody makes gasoline cans out of Model A fuel filter screen material.
