EVAP Pressure/Purge Diagnostic Station

The J 41413 EVAP Pressure/Purge Diagnostic Station is used to help locate leaks in the EVAP system. The station 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 41415-40 Fuel Tank Cap Adapter is used to adapt the J 41413 to the fuel filler neck. Pressurizing the EVAP system at the fuel filler neck allows testing of the filler neck and the fuel fill cap on vehicles with Onboard Refueling Vapor Recovery (ORVR).

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