Every time I see these kinds of postings for postwar Packards I always think the same thing. Sometimes I even post the biggest cure I ever knew from back in the 1970s. But no one has ever commented that it helped. Anyway, I'll do it again.

Check the flex coupling in the fuel line where it leads to or from the fuel pump. What do you check for? Fine hairline cracks. You often have to remove the flex coupling and look at it very up close in good light. If you bend it and hairline cracks show up ... THAT is the problem.

Used to see this all, all, all the time on postwar Packards-especially V-8s. It is not a visually obvious problem unless you do very close inspection. And it often does not make itself known with a leak. But it is the cause of many problems like this.

The mechanic at Frost & French Packard dealership in Los Angeles decades ago told me people would bring cars in after buying a new fuel pump and would swear they sold them a bad pump... but the real problem the whole time was never the pump or the carb. It was the flex coupling in the fuel line.

These couplings often look perfectly fine, but under pressure all kinds of things happen: they leak, they suck air, deform, etc. etc. It's a cheap fix, but almost no one ever tries it until they've already spent a pantload of money and wasted a lot of time.

Anyway... for what it's worth...
