I long ago read an article in Skinned Knuckles magazine written by a fellow that had bought an old Cadillac at a bargain price because it ran erratically and occasionally stalled. All the 'usual suspects' had been addressed and corrected; however, the new owner found a few places in the metal fuel line that had some dents and/or kinks. The line was replaced and the car ran superbly ever after. The new owner attributed the problem to cavitation of the gas in the line due to the kinks and dents. Sounds plausible to me. I don't know old Cadillacs, but most older American cars employed a mechanical fuel pump driven by the engine cam, so the lines would have been upstream of the pump.
