Since the fuel level difference follows the switching of caps, makes
me wonder if the
vent on one of the caps is plugged up?

Due to the way things have been swapped around over the years, I’d
be absolutely certain the fuel system you have matches the
configuration from the factory before switching to unvented caps.
The penalty for being wrong is much more severe than if you put
vented caps on a system that doesn’t need them.
