Hey ya'll I just came across this thread while troubleshooting a P0172 on my 93 Pickup that has a 2003 2rzfe swap. Back in 2012 when I did the swap I ran the charcoal can straight to the intake manifold vacuum. What happened is that when the gas cap was tight and pressure in the tank built up, the engine would suck a larger quantity of vapor up to the engine. This would make it bog down some and eventually throw a P0172

Moral of the story. Don't run the tank vapor straight to the intake vacuum all the time or the ECM could detect an overrich fuel trim issue and pop the P0172 which in turn causes the ECM to pull fuel and it will run like crap.

Just throwing this out there to help ya'll out since this thread helped me out!

Sounds like you should just vent to the atmosphere like I ended up doing. Do the FATS system in case if a roll over. Keeps it simple and easy.

I'm thinking I need to do this. My charcoal can is dead. They don't even sell new ones anymore, so I pretty much have to find a good used one.

With this FATS setup does the Fram filter get rid of some of those harsh vapors?

I actually found some more info on it here. https://www.pirate4x4.com/threads/fats-fuel-air-trap-system.243815/

Yeah the filter will help keep a little bit of fumes from escaping as freely. I had a filter on mine but somehow I broke it off and never ended up replacing it. When I redo things, I'll add the filter back in.
