Centrifugal pumps need priming as they do not create a vacuum. Engine fuel pumps do creat a vacuum thus do not need priming. You will not find any Packard or other US car service manual of the era saying anything about priming.

When replacing a fuel pump you don't have to prime it. If you run your tank dry adn put in a few gallons yoiu don;t have to prime it.

Squirting gas into the carb replaces the action of a carburetor accelerator pump that is not working properly.

Some of this stuff I can't let go without comment as it leads fellow forum menbers and others down the wrong path.

One of these days I'll tell everyone about my 54 1/2 experimental Packard 12. It has a V6 cyl engine in the trunk powering the front wheels and a radial 6 under the hood powering the rear wheels. 4 wheel steering, turbo charged air conditioning and 15,000 rpm muffler clothespins.
