Correct sir! So I started like this:
I originally did 2-dumb things to finally figure this one out:
1) (original picture has been destroyed)
I looped the red-dot port and the blue-dot port on the tank together. Logically they went to the vapor canister and after eliminating the vapor canister you can just tie these together like they were never there right?
Wrong! The tank magically won't let any air back in after fuel has been displaced (run out through the petcock). Eventually when enough vacuum builds in the tank the engine will stop running. Bad! Very bad! (more annoying actually)
2) I blocked the blue-dot port and vented the red-dot port:
This actually works. The tank vents all prim and proper, but technically if you're really sloshing around gasoline can escape up and down through this port. So the BEST way is:
3) Block the red-dot port and vent the blue-dot port:
I also threw in a cheap inline filter and PCV valve (perhaps overkill, but I want any air going into the tank as clean as possible and I don't want anything coming back UP.
And that's the way it's been for nearly 6 months now
