What if you have new compressor, hoses, dryer and governor, and still no air build up?

[@abdallanur9521]

Check your tanks

[@manuelsalgado8510]

Check the hose coming from air compressor, probably stuck. What kind truck , Volvo?

[@VideoByPatrick]

[@desitruckersinu.s.a2797]

As long compressor building pressure you should have no issue it may take little longer to build air. You can always check the pressure of air compressor by putting a Guage on other side of line. If it's too low than it's better to replace but make sure that the line have no leak or it will show low pressure.
