Fuel pressure drop

Hi all. I wonder if someone had the same fenome.
Before engine start - fuel pressure is ok. After starting, fuel pressure drop to 2.6bar.
All tests done with above 14V
Fuel pressure sensor is in good condition and checked with another analogue gauge.
After disconnected the pipe between the airbox and the pressure regulator, all fine, pressure stayed 2.9,in both - stop and running engine.
Next I operate the engine with the pipe and w/o the air filter - pressure drop.
So the conclusion is that something happens in the airbox.
The question is what do you think about this fenome?
