I just installed my fuel filler in a similar spot on my GMC. I don’t have a vented cap so I installed the rollover vent about 3-4 inches above the fuel cap. I still get a little bit of fuel pushing out of the vent after I fill up and the truck sits-I assume the fuel is expanding with heat and pushing up the vent line. If you have a vented cap, I suggest you route the vent line to the filler neck to avoid my situation.
