I have a vented cap. There is another vent that was coming off the tank. I ran a hose from that out under the vehicle.

I'm thinking the vented cap should be enough, and the other vent coming off the tank needs to be plugged. Vented caps don't let out a lot of fumes unless there is pressure build up from the sun shining on the truck after you park it. The vented cap's function is mostly to let air into the tank as you use up the gas.
