Let me start by saying I know this has nothing to do with dodge cummins but I needed to run this buy some people. I have a 1994 ford ltl9000 with a 3406 cat 435 in it. I am having trouble with the air system... It won't build past 75 pounds of air it will build up to that point quick so the compressor is still good. Air governor? Or some other valve. Any help is much appreciated thanks in advance.
