Pressurizing a line may not always reveal the leak. Sometimes a gasket
or "o" ring acts as a one way valve.
If the pressure test doesn't reveal the leak; try this.
Apply a vacuum pump to the line. Then paint the joints with a very thick
oil.
As the thick oil is sucked into the leak the vacuum will rise slightly
when the leak is plugged.
Lacking a good vacuum gauge you can fabricate one from a piece of clear
plastic tubing bent into a U shape.
The technical name of that is a manometer.
