p0442 put a smoke machine on it at the house and turned the vent valve on. has a 40 thousandths leak. does anybody have a diagram of the evap system for this truck?? how do you test the vacuum cut valve and bypass valve on this truck? im getting smoke flowing out of the canister with the vent valve closed. one hose on the valve goes to the filter then the other goes a rubber hose that runs to the tank. shouldn't there be no flow when the valve is closed. I repaired 2 rotted hoses I did see smoke coming out of
