FiTech EFI system

If your cars had a fuel vapor separator you might be able to T in there. My Cuda had 4 lines from tank vents (see my previous pic's/diagrams)
I T'd my FCC vent in back near the tank with a line I ran. I tapped into the second tallest vent in the ECS so if the tank splashed up and in it returned to the tank not the FCC vent.

To anyone who read a posters negative comment I can assure you I have been very happy from day one with my FiTech. A buddy came over when I installed it and fired it up and he was shocked that it started and ran so easily.

I just had to start over due to incorrect timing because my damper had slipped. So I had to rest the throttle blades to correct the IAC reading at idle. So the car has to do some relearning. The car ran great even with the bad damper and less than 20 degrees total timing, even better now. It still needs to relearn and seemed to stay right with an LS swapped Nissan until I think I accidentally hit my rev limiter which is over 6K rpm and since the car had provisions to quick release his front bumper cover he probably had an intercooler..... I still don't have a good fuel map in the upper RPM's since it just hadn't been there yet.
