Air breaks on Mack dump truck 2001

Crash ยท 2016-03-04 11:31

Changed governor, air dryer, and won't build pressure over 70 psi unless I remove hose going from regulator to side of compressor . put gauge on top of compressor and held pressure. Can anyone give me an idea of what's going on? Thanks CRASH

    Not sure I understand, what regulator line to the compressor? Do you mean the line from air governor to the unloader port on the compressor? Any chance of posting a picture of the compressor pointing to the line? Also is is best to keep posting to the original post so people don't waste time giving answers you already have been givin!
