I can't build air pressure. I replaced the governor, still nothing. Air is coming out the bottom of the air drier, I know the compressor is working. Now what?

you ought to rebuild the purge valve or replace the air dryer

looks like the purge valve is leaking

I figure if air is coming out the dryer the compressor is pumping air
just my thoughts
