On that one you want the vent several inches higher than the filler.
The issue is that if you fill the tank and park the truck out in the sun the gas will heat up and expand and if the vent isn't high enough the expansion will push gas out the vent or in my case the vented cap. I made that mistake whne going to an event where I wanted to be on the highway for a long trip home right after the event and had gas leaking out the vented cap while sitting at the event. My bad that time for not leaving any room for expansion.
