I recently installed a Holley Sniper and am wondering if this Gas Cap will be vented well enough so that I do not have to have a secondary vent coming off the tank itself. I currently have a secondary vent line off the tank running up into my rear bed pillar, the only issue is when doing harder trails I get a lot of slosh and spillage out of this vent line. Hoping to eliminate the smell and the waste of fuel. Thanks

The fuel cap lets air in, not out. So secondary venting will likely still be needed. There are check valves on the market that can be added so fuel will not escape, but allows the tank to breath. Just search online Rollover vent valve Or Fuel vent valve.
