Whare is the air dryer regulator. That's not the governor is it?
Both tanks fill equally and I only loose air at night down to 90psi I am always looking for leaks and have changed a bunch of push fittings.

it looks like this...



Like I said.. leaks that only happen above 90 PSI.. can usually only be found while the pressures are above this ...+ the key-switch in the dash has to remain on but the engine not running.

Someone has to run the truck and build the air all the way up to 125+ psi for both tanks.. then turn the key-switch off.. only barely long enough that the engine stops running, then right back into the on position, so that all the systems stay active without the engine turning. Then jump out real quick and listen for hissing, air leaks, etc. right away before the air bleeds off down to 90-psi.
