Predator 3500 spewing gas out of the canister vent

I have a brand new Predator 3500 inverter generator. Only 2 hours on it. I just filled it all the way up with gas and its been sitting in the back of my truck all day in 95 degree heat. I noticed gas all over the bed of my truck so I took the side cover off and witnessed it spewing gas out of the Open Canister Male Nipple as shown in the top right of the attached photo.

Does this mean I've got too much fuel in it or is there a greater problem?

    Need to leave a 1/2 inch above fuel for expansion

    x2 on the gas expanding, take some out a quart should do, then try the in the heat again, bet everything is fine.

    Sounds like the gas system needs some kind of vent. One of my gas cans will shoot gas when opened during high heat. Never had this happen on one of my Hondas but I don't recall ever filling it up and leaving it sitting in the sun.

    My best suggestion is "don't do that."
