Leaking air when I press the gas and when I release service brake

Ok will take a pic of it hopefully u still around. If I disconnect all the lines from the chamber it would have to be that one you think?

 

Will check now thanks.

 

Is this the one you’d speaking off and to removes those two small line? Again thank you so much for the help.

 

I also remove this lines of all the chambers to see if they wet the issue but it still does it.

 

Hey so I disconnected like you said and air is coming in on 1 (photo provided ) and coming of 2 does that mean it’s bad?

 

Air is coming in on 1 and leaving on 2

 

Sorry for all the reply and when I cover 2 with my finger it stop leaking.
