8.3l ISC pump is dripping on the air compressor, cant see any lines leaking .It would appear that its leaking from the mid section of the pump. Is there a out of sight leak that can be tightened or o-ring replaced ect...?

its a weep hole like a water pump , first signs of it getting bad next sign will be an extended crank-hard start it will need to be replaced
