I need to figure out what to do about this. When I have a full tank and drive agressive I get a overwhelming gas smell.
Do you use your charcol filter?
I am at a loss for what to do.

I have seen mention of using a vented gas cap?
I was wondering if there was a check valve near the tank that released excess pressure to the atmosphere if it could not go through the charcoal canister?

There are 3 lines running from your fuel tank. Fuel supply, Fuel Return, and the vent line which goes to the charcol cannister. My vent line is not hooked up to anything right now.

well my opinion is you can do it 3 ways.
old school: cap the vent line and run a vented cap, like a pre 67? car, you'll prolly still smell gas here and there, but since its the way it wass done back in the day it sould be safe
stock: put the damn charcoal cannister back in, it weighs almost nothing, if you just hook the gas tank vent line to it it will take care of the smell. if you wanted a gold star by your name you could tee the other side of the cannister into the pcv system, like stock. in the stock setup they have a line going to the tbody so they can burn the vapors, and stuff, and theres a check valve so under boost the other end of the pcv is in front of the turbo. no gas smell here
way 3 is the way you have it, i dont like it theres a gas smell under the hood, and that should be reserved for the rest of the fuel system, i like to use my nose to diagnose cars
