EVAP Pressure/Purge Diagnostic Station




The J 41413 EVAP Pressure/Purge Diagnostic Station (2) is used to help locate leaks in the EVAP system. It provides a clean, dry, regulated supply of nitrogen to pressurize the EVAP system. Refer to the directions on the cart for proper operation.

The J 41416 Ultrasonic Leak Detector is then used to pinpoint the source of the leak.
