Pull the filler neck out. Brass or weld a 3/8 nipple in it. Make sure your fuel cap is a two way and release pressure. Thats the only thing that I would know to do short of leaving it vented under the truck. we are in the same boat with different setups..

I am going to make mine work I am just not sure how yet, I think my first attempt will be to T my original vent line to the command center vent and leave one side open under the hood. If I never smell gas guess what its going to stay like!!!!! If it does produce more vapors than the factory vent line under the truck I will back up and punt. My dilemma is if I run another line back to the tank and leave the original vent line and it does pressurize my tank it will push even worse vapors from the 25 gallon tank under the hood through the original vent line than the command center vent would alone.
