Pressure test - found a leak

Hi Guys,

the venturi valve was leaking. After changing this, i did another test. around 1+ bar (around 14 PSI) i heard a silent hiss noise from the right side in the direction of the secondary air pump. I gave more boost and it made "plopp" "shhhhhhhhhh" Some line popped obviously off. Thats what it sounds like now.

My guess is, that the fuel pressure line came off, cause the noise comes from behinde the secondary air pump.

What do u guys think?
