P0442-"small evap leak" fix for 7th gen Celica

Due to a P0442 code, I built a smoke machine and found the evap leak was on top of the gas tank but was not a part of the fuel pump cover. It was the fuel tank over flow check valve. I replaced the check valve and gasket and no more leak! I got the OEM parts on Ebay for less than $70. Fuel tank held in place with 2 straps and 4 bolts-(I said 4 straps in the video).
