The fuel pump on my '48 3100 drains back when sitting, as evidenced by the level of gas in the glass dome getting significantly lower than when it's running. Is this normal? I don't have any problem starting the truck, even after it has sat for two to three weeks.

You may have a bit of crud holding the valve open just a bit. It shouldn't drain back. If it were me I'd buy a spare pump to keep on hand in case that one gives it up. If you haven't already done so it wouldn't hurt to put a filter between the tank and fuel pump.
