I occasionally see a question posted about the glass bowl on a fuel filter or pump not filling completely. The good news is that they should not fill completely.

I shot a video to show the fuel levels in my Durex Moraine GM #986640 fuel filter, and my '52-'55 glass bowl fuel pump that I cobbled together.

After I turn off the motor, the glass bowl on the fuel filter usually fills completely. I assume that ...
> Pressure remains in the line between the pump and the carb.
> The pump does not allow the pressure to reverse through the pump.
> So the bowl fills with the pressurized fuel in the line as air and fuel ooze past the float seat in the carb.

Hope that the video answers the question about fuel level.
