Looks like an overpressure release valve – which is probably stuck. If you have the manual, check the parts diagram. You could also contact the company directly and just ask them :)

Go to Youtube, and type in “my compressor won’t build up pressure”...There are several youtube videos to tell or show you how to fix the problem…..

did you spray some soapy water on all the connections ?

if any fitting is the culprit, it will produce bubbles like a leak in a tire.

have you been tinkering with any of the adjustments under the gray plastic cap ??

That looks like a cold start valve to me, occasionally they’ll stick open and you’ll never get past 10-15psi from a completely empty tank. You can remove it and clean out any dust or tiny debris or get a new one for under $10.
