I wanted to take out the vapor return lines that go from my q-jet to the fuel tank.

I also have the charcoal canister to be taken out.

I am welding in some new floor areas and I want all fuel lines out of the way to do this.

Can I take the entire return fuel lines out, and the just plug the port on the carburator without running into any issues? Am I going to have to re-calibrate my carb? Emmissions are NO concerns. I also have a vented gas cap.
