I’m installing the Red Line GM evap kit on my 79. I hooked everything up but I cannot find the tank line check valve.
I expected it to be in the access panel near the filler neck and the vapor chamber - but there’s nothing there. I unbolted it leaned it forward and it’s not behind it either.
There’s nothing under the car or under the hood either.
I was going to add a factory check valve in the line from the evap chamber to the tank - but it’s really weird that it’s missing. I didn’t want to double up check valves if there is somewhere else to look.
I’m following the emissions manual from
1980 - my 40 is a 9/79
