Hello everyone I have a 72 which has had all the eec equipment removed. The fuel tank vent tubes are all capped, and has a non vented gas cap. Just want to make sure 72 did not come with a vented gas cap. I do get a large swoosh noise when the cap is removed. To alleviate this can I run some sort of vent from the drivers side tube? Does it have to be as high as the filler neck tube? Also any recommendations on a new non eec tank?
