EVAP leak help. 1988 dodge aries?

there is no help tool for that old of a model car it wasn't equipped for a smoke test but what you can do is test the gas cap and all the lines including the one from the canister tank on it,those cars had many vacuum lines on them and any one of them will cause it to fail a test like that,check the ones that go from the canister tank real closely ,that may be the problem with it,good luck with it.
