Hey Gents,
I have a 1970 RR California car with the Evaporative Control System (ECS). that means that in addition to he fuel line, my tank has four hoses which run from the passenger side of the tank up into a canister in the trunk, and a steel fuel line which then runs forward all the way to the engine bay where it, theoretically, allows fuel tank vapors to be consumed by the carb when running, or carb vapors to condense into the tank when parked. By modern standards, this emission control system is a joke, particularly given that the Holley carb I am running does not use that line!
So can I just cut off / block off all of those lines at the tank? One of them may be necessary as a tank vent (I'll check) but the others just seem like needless extra complexity. This is a mechanical question, not one of legality. I assume that I should not tamper with the factory emission system, even such as it is, but really, it's a joke. Carb vapors? Seriously?
