First time poster. I have a 67 Fury drop top with a 318 and new carter 2bbl. I have a pretty strong fuel smell when driving. Not on start up though. Only seems present when the top is down. Smell existed with both old and new carb. Added dye to the gas to find leaks with a black light. None to be found. Manifold has no air leaks, Air leak at exhaust connecting to the manifold. No leak at gas tank that I can find and I added a vented cap. Look forward to your suggestions and thanks in advance.
