Solenoids not working with code

Hello! My team is new to pneumatics this year and our pneumatic setup isn’t holding any air in the tank. As soon as we fill the reservoir with the bike pump, the air comes out of the release on the solenoid. All the fittings aren’t leaking because when I test the airflow, everything seems to be airtight (again i just can’t fill the reservoir). I’ve also tried using the code from the official vex website to try and control the solenoid but nothing has worked. Any help would be much appreciated! I’ve attached a photo of our setup.

ps our kit didn’t come with a shut off valve but it did come with a pressure regulator .

Did you make sure that your input and output tubes are in the right ports? Your input tube should be in port P.
