The evap system is deleted and I have ptfe lines and it still smells like gas pretty bad, but as far as I can tell the stock stuff is still in place but the tank still has issues venting. I have to put gas in very slow.
I deleted my EVAP system as well and never experienced a gas smell. I left the oem vent line open and its routed to the end of the tank. What type of fuel lines are you using? PTFE lines?
