Awesome pix. Smog inspectors in Ca, performs LPFET on 1976-1995 model year is check EVAP systems by crimp or plug the EVAP hose at EVAP canister and installs gas cap adapter, insert the cap adapter with compressed nitrogen ( very low PSI) to see if the system is holding the pressure for amount of time. If not hold pressure after time lapsed, it will fail for leaked system. Common bad hoses. EVAP canisters are subject to visual inspect for sign of damaged or disconnected hoses, nothing do with the OEM EVAP canisters. Modified canisters are illegal. Gas cap function test are applied to 1976 to 1999 model year.
