    I've recently installed a new tu-flo 550 air compressor. I also installed a new governor. I've tried to adjust that as well in to restrict air and out but still no change the compressor continues to want to climb past 130psi but I turn either the truck off or dump the air. Any help would be GREATLY APPRECIATED AS IM OUT OF WORK UNTIL ITS REPAIRED

    Tried the old/different gvrnr? New does not automatically mean properly working. QC may give a glitch here and there.

    I’ve had governors on new AD- series dryers go as high as 140 before they unload. Most unload at 130-135psi. As long as it’s cutting back in at a reasonable pressure I wouldn’t worry about it. If it doesn’t unload, or cut in when you fan it down you probably got a bad governor.

    Double check for any plugs that may have been (or needed to be) transferred to new part.

    You did put a gasket between the compressor and governor?
    You did not put a plug in the hole where the governor bolts to the compressor?
