fuel filler vent hose questions

[blue beast j10]

was wondering how to tell what style I have only seen the one on my truck which is in the side of the bed in front of rear wheel, kind of makes me think it's side fill, if so where can I get these or what will work to replace them?

You have to get under the truck and look to see where the fill hose goes into the tank itself. A side fill tank has the filler go into the side of the tank, while a front fill has the filler go into the front side of the tank
