John does the leak seem to be getting worse or is it staying the same? If it is staying the same perhaps reducing the pressure will help, if it is getting progressively worse reducing the pressure proably won't help. if it's is a crack forming in the tubes as opposed to a pinhole crack may widen with vibration on your trip to macungie. If you have time before your trip pulling it would proably be best route, would be one less thing to worry about.
