Abstract
A fuel cap leakage tester is provided comprising a fuel cap support, a pressure source, and a monitor. The fuel cap support is formed to included a test chamber and is adapted to receive a fuel cap to be tested in the test chamber to establish a pressurizable region, therein and a sealed connection between the fuel cap to be tested and the fuel cap support. The monitor is positioned to communicate with the pressurizable region formed in the fuel cap support and is configured to measure air pressure in the pressurizable region. The fuel cap leakage tester further comprises a system for communicating a flow of pressurized air from the pressure source to the pressurizable region with a predetermined pressure drop of the pressurized air therebetween. The monitor measures the pressure level of the pressurized air in the pressurizable region to determine whether the fuel cap to be tested meets or exceeds a predetermined leakage flow rate.
