Good one, Jerry.
I have a '56 Cadillac with a factory glass filter between the fuel pump and carburetor. It's never full of gas.
I've gotten used to being able to have a visual reference on whether or not the fuel pump is working so I install the clear glass inline ones on everything I own.
In the case of the '50 3100, its original fuel pump had the clear glass bowl attached to it but the replacement pump doesn't have one. The only place I've found that sells the original style pump with the glass filter bowl on top is Golden State Chevys - $75.
