champagnegold 0 Report post Posted July 16, 2004 It sure looks like I'm leaking gas from the tank through the pop-open gas cap. My Mach 1 has been lowered and I'm wondering if that, combined with acceleration will slosh gas up through the filler neck and out the cap. They don't seem to seal airtight anyway. Anyway have similar problems? And, any ideas for fixes? Thanks Share this post Link to post Share on other sites
