False positive during second leak test right tank

During the second pressure test of the right fuel tank it looked like there was a leak.

I removed the tank from the wing and did a soap bubble test.
It seems that I did a better job in taping of the fuel cap during the first leak test.
This time air could escape through the fuel cap and transparent tape:

To be absolutely sure I removed the tape, cleaned the tank with Acetone and added 2 layers of tape:

I also fixated the transparent tube of my manometer a bit better because the tube could move a bit which gives incorrect readings.

Next is to do another leak test.
