Does anyone know what these two extra lines are

Does anyone know what these two extra lines are? This is in the back of the van on the driver side, above the gas tank. The four lines are the emissions lines that go into the gas tank, but I don’t know what the other two are for. I assume one is to send vapors to the charcoal canister, but what is the other one for? Anyone? thanks

Might be filler overflow?

How about listing what you're working on? Year, fuel type, chassis GVW?

Don’t think that will make a difference in this case, but it’s a 1970 ford e100 econoline w CA emissions system

here is a ford service manual you might think about checking into. i have one for each of my vans and since they are from Ford and for 1970 only, They are much more detailed then other manuals.
Im not sure if this will show CA emissions but it does have a section on emissions

I would think it could be one line to the charcoal can and one line from the charcoal can to atmosphere.

Did you happen to take any pictures of the gas tank after you removed it from the van? Perhaps it has some connectors that would be helpful in someone identifying where the lines go.
None of those lines run straight through that steel channel/frame?
Do all of the lines run forward towards the front of the van, inside of the channel/frame?
They have to exit somewhere.
Again some more pictures backed away from the hoses would be good so we can get a better idea of the area. Some pictures on both sides along that whole metal frame would be great


You might try calling these folks and see if they can tell you if this book has CA emissions diagrams in it.
