Here is a description of how your 4 vent tank system was hooked up: Fixing 1970s Evaporation Control Systems

I'd replace the line from the tank as a 1st step. After 48 years, some internal scaly rust could have fallen in when you were working with it; you just don't know. One poster one FABO once reported finding a bug blocking the line LOL

Ok, really not enjoying thinking about bugs being trapped in the line while I'm working on it and running out of there when I disconnect them LOL. That is a good thought though, it is an older set of lines for sure, there could be any number of issues with them. I've never actually re-plumbed one of these, are the lines easily accessible in the frame rails or am I setting aside a couple of hours to fight with them?

Since the evap can was removed from the system, I hadn't hooked those lines back up to the tank, I assumed they were just cut somewhere up further and there wouldn't be a difference. I guess I can lower the tank and put them back on, but I'm not sure how much that matters.
