Even tho the cap is new it might be defective.

Pressure test it.

Re: Upper Hose Stiff

I have no idea if this would make the hose stiff, but ...

When you swapped to carb, did you retain the serp belt system?

I ask because my thought was maybe you have the wrong water pump. If you kept the serp belt system, you need a reverse rotation water pump, if you went with any other belt system, you need a standard rotation pump.
