A fuel cap tester kit containing a plurality of fuel cap adapters, wherein each adapter has a mouth opening, outer rim, cap receiving chamber, air supply passageway and a fuel cap connection opening and with each fuel cap opening being configured to engage and retain a different and specifically configured fuel cap, and wherein each adapter is also provided with a threaded base connection that cooperates with a complimentary threaded connection on a test base that is fluidly connected to a pressure source and tester apparatus and wherein the base connectors of each adapter are configured alike so that each adapter can be connected to the single threaded connector in the test base to permit testing of different size fuel caps dependent on the adapter threaded into the test base, where the tester kit is used to decide upon quality of fuel caps under test by determining a leakage rate of pressurized air from the cap-receiving chamber through the mouth opening.

[ We claim:] [1.] A fuel cap tester kit having component parts capable of being assembled in the field at a fuel cap leakage testing site to provide a fuel cap leakage tester configured to accept and test more than one style of fuel cap, each fuel cap having a filler neck closure portion and an outer shell coupled to the filler neck closure portion, the kit comprising the combination ofa test base formed to include a base chamber and a pressurized air supply conduit in fluid communication with the base chamber andat least two cap adapters, each cap adapter being formed to include a pressurized air supply passageway and a cap-receiving chamber adapted to receive a fuel cap to be tested therein and connected to the pressurized air supply passageway, each cap adapter including a threaded connector adapted to engage a cooperating configured threaded connector in the test base to communicate pressurized air from the base chamber to the cap-receiving chamber through the pressurized air supply passageway, an outer rim providing a mouth opening into the cap-receiving chamber, and a retainer adapted to mechanically fasten and retain a filler neck closure portion of a fuel cap to be tested in a mounted position extending into the cap-receiving chamber and closing the mouth opening into the cap-receiving chamber preparatory to determining a leakage rate of pressurized air from the cap-receiving chamber through the mouth opening.
