Hey guys i have the keyed alike vented gas caps from wild horses and im curious. Do they just let air in?(or out) reason i ask is i capped off the vent lines and noticed when i filled it up yesterday it had a pressure build up when pulled the cap off. It hasnt stalled on me so im assuming it lets air in... Just not sure. Is that pressure a bad thing if it cant get out? I searched around but couldnt find the info i was looking for.
