So the line with the white tape goes to the air cleaner, I understand and found where that connects. what I do not know is why is there a T in that line and were did or should it go? If not needed can I delete the T ?

Question #2
The very small pvc line with green tape, hard to see, does that go to the port on the carb with the green tape? Lots of tubes with screws plugging them that I didnt do so I am just trying to confirm and re plumb these lines

Didnt know if a carb pic would be helpful , there is a hose plugged with a screw that I need to figure out...unless that is where the last vapor line connects??

In what form? Burnt wood or some other form of incinerated substance?
I have used charcoal from fish tank filters before (new not used). It comes in a fabric bag and seemed to work to remove soldering fumes sucked through a small fan.

That plugged hose is not tothe cannister. I forget where it goes I'll look tomorrow. I think it's labeled port b check your emissions sticker. Pull back on your pic so I can see both ends of the mystery hose. I think it goes to a nipple on the air cleaner.

Ken,

we had same issue. PO did the charcoal canister delete 2 port sending unit as well. Found that same steel line under radiator shroud and PO cut it drivers side bottom and that was it. We smelled gas all the time and could not find at the time a canister. I made a small charcoal filter out of a fuel filter and a fuel vent and mounted it on drivers side firewall. Fixed the gas smell and have never looked back.

Not sure if that is what your wanting but here are a few pics

I understand the whole process but just wanted to ask if you just added the charcoal inside the glass filter housing around the center threaded with the filter screen inside or is there something I might be missing because the center that the filter ends screw onto doesn’t leave a lot of room for the charcoal and advise would be greatly appreciated Thanks
