Abstract
An evaporative emissions test apparatus is provided including a tester adapted to pressure test a vehicle fuel holding system for vapor emitting leaks. The test apparatus includes an adapter configured to sealingly engage the access port for filling the fuel tank, the adapter being further configured to sealingly receive the vehicle fuel cap so that the vehicle fuel holding system including the fuel cap can be tested as a unit. The tester includes a connector for connecting to the adapter, and further includes a second connector for connecting to a pressure source for pressurizing the fuel holding system and fuel vapor control system to a predetermined pressure. The tester also includes a sensor for sensing the pressure over time, a timer for indicating the passage of a predetermined amount of time, and a display generator and display for indicating if the pressure in the atmosphere is acceptable after passage of the predetermined amount of time.
