The Evaporative Emission System Tester is used to help locate leaks in the evaporative emission (EVAP) system. The EEST provides a clean, dry, regulated supply of nitrogen to pressurize the EVAP system. It also provides smoke to help in locating the leak source. Refer to the directions on the cart for proper operation.
The Fuel Tank Cap Adapter is used to adapt the to the fuel filler neck. Pressurizing, or inducing smoke to 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 High Intensity White Light is used to help locate the leak source.
