1994 FZJ80 Failed Evap Controls Smog (1 Viewer)

Hey Mud,
Looking for bit of assistance here. Took my 94 in for smog and it passed everything EXCEPT the Fuel Evaporative Controls Functional test. Tech explained that they pressurize the tank and if it leaks a certain amount then it fails. Says likely a hose or something.

Before I go dropping the fuel tank and pulling hoses off of everything, has anyone had this specific failure before? Any sure fire spots to check first? Thanks in advance.

Make or rent a smoke machine and hook it up to the hose connected to charcoal canister. When mine failed it actually just ended up being a loose hose clamp on one of the lines to the canister. Once I tightened it I passed.

Right on. Thanks for the insight.

Welp... got the smoke machine and put it to work, but couldn't find any leaks! I used the gas cap adapter and charged the tank, nothing... I pulled the hoses off the evap canister and tested both sides of each... nothing!

Any other lines or hoses I'm missing?
