I've had a fairly new, like 3 years old rubber line to the fuel pump crack. It did not leak fuel as there is no pressure there, but would leak enough air to make it hard to start after sitting for long periods. Same symptoms as the bad gasket at the glass sediment bowl as mentioned above. I like the rubber bowl gaskets if you can find them.

There is a special grease used in the aviation world that will not wash off with gasoline, so its good for the cork gaskets on the glass bowl. Sorry, I do not know the product name, only that its very expensive and my buddy who was an A&P would give me a little dab for my cars.
