74 FJ40 fuel vapor line and charcoal canister diagram

[hobbes]

Wow your schematic I understand the hook up shown but it's contrary to others schematics that led me to the separator connecting to the bottom of canister and the top connecting to the manifold. I was wondering what the second port on top of the canister connected to? Compare engineer8000 schematic to the one Mark FJ40 just posted. Which is right to me the fumes need to be pulled through the charcoal. So the bottom can't be atmosphere otherwise the fumes would not be pulled through the charcoal but bounce across the top of the charcoal? Just want a discussion on the proper way to connect the canister so the charcoal can absorb the fumes until pulled through to the manifold?

That schematic doesn’t show the check valve after the fuel separator.

Some photos…

Here I’m holding back my ultra-cool plug-in trailer wiring harness (Coolerman) showing the charcoal canister output hose that goes to the hard line that crosses the firewall.

Now I know why I can’t find the BVSV on my bench. I forgot I had installed it! It’s the purple thing that has two caps on it.

My charcoal canister line terminates at this filter. The empty black bracket behind it is for the VSV. It’s off a 60 series I think.

Sorry for The late reply? I thought I had ordered the the manual VSV valve before I left PHX. I thought it had been shipped and delivered? But I need to reorder it and don't remember where from. Any recommendations where I can get the VSV valve?

What I'm looking for is a vaccum operated two way valve. This I can put between the canister and Vaccum port on the intake or carb..

I didn’t know those were still around. I might have my old busted up one somewhere. I actually never thought of using that one. I just bought the newer version since that old version requires a lot more than just vacuum to work.
