If the fuel hose is porous it will suck in air which has humidity in it. The moisture cannot wind up in the tank as the fuel is flowing in the opposite direction.

Yes if you look at an older hose in the light you will see tiny cracks, they are caused by ozone deterioration. The cracks are usually in the outside protective layer and do not cause leaks. Tires also are affected by ozone and if you look at older tires you will see those tiny cracks, but tires are not going flat in masses from them.

If the cracking is such a problem on the V8 it would be a problem on all cars using a mechanical fuel pump, that would be 100% of cars manufactured from 1932 until fuel injection was introduced. 37 Plymouth, Cadillac V16, Corvair etc

Yes it is possible to spend thousands to get tot he correct repair but it can be avoided. Using a pressure/vacuum gauge ( about $15) will diagnose the fuel delivery system.

The problem described is a common one most often blamed on "drain back" (which is impossible)
It is a non-functioning accelerator pump and/or choke adjustment.
