Not likely at all. If you had gasoline puddled in the intake, the engine could not run. You have a carburetor issue. The drain pipe is doing what it is supposed to do, which is to prevent liquid gasoline from puddling in the intake manifold when the engine is shut down or if the choke is over-used. It's a good feature.

Some carburetors cannot leak gasoline unless the float needle and seat or the float itself are out of order or out of adjustment. Others can leak gasoline even if the float, needle and seat are in perfect order and perfect adjustment. Some Stromberg carburetors used on 1930s Packards had a feature at the bottom of the carburetor bowl that could collect water and corrode or freeze and crack. That could cause internal gasoline leakage.

I can't be absolutely certain from here, but I'm almost certain you have some kind of carburetor issue.

It is a Stromberg. And it has a heat shield on it. I just pulled the air cleaner off and pulled it outside, the instant I shut it off gas started dripping out that tube. I looked in the carb and there is nothing. I'm missing something somewhere.

Engine vacuum holds the ball check vavle in the drain line shut, so if it starts leaking from the drain as soon as you turn the car off, that means it is likely leaking while running.

I agree, given you have a factory mechanical pump, it sounds like a carb issue.

The gasoline is leaking from the carburetor. The drain pipe is simply doing what it is designed to do.

There is a lot of information in this site's Literature Archive service section on carburetors. The 1936 shop manual has some carburetor illustrations and information. Your carburetor may simply need to be cleaned and adjusted, or it may need new parts. I would not take it apart unless I had experience working on carburetors, and had adequate tools on hand. It's almost certain that new gaskets and fiber washers would be needed. Rebuilt carburetors are available on an exchange basis. Dirt in the fuel system will cause problems with a new or rebuilt carburetor sooner or later. So will old stale gasoline. The problem isn't likely to fix itself, and attempting repairs based on guesses is unlikely to get good results.
