That's normal.

The ECU doesn't monitor the fuel pressure. The regulator is a mechanical inner tank device.

I would say the fuel sender (under the tank) is at fault. You can perhaps try to clean it. But taking it apart
require taking the tank off (preferably mostly empty, you can lie it on one side and shim it at the bottom side
to get the remaining fuel level below the sender hole). You can change it too.
