The flammable fumes is a spell that normally deals poison damage but can potentially deal fire damage under specific conditions. It only has the poison trait though and no fire trait. Usually descriptions are pretty good at specifying trait changes but there none for this spell. I assume it’s on purpose becuse fire effects trigger it, which could mean it would trigger itself if it had the fire trait?
Is it a poison spell through and through for both the cloud and explosion damage, or should it replace the poison trait with fire for the explosion?

Strict RAW, it doesn't have the fire trait and nothing adds it.
So rule something that makes sense.
The fire effect that triggers the explosion would generally have the fire trait. Ruling that the fire trait from that triggering effect has its area extended to the area of the Flammable Fumes would make sense. So if it is non-magical fire that triggers the explosion, then the fire damage from the explosion might also be non-magical fire. But maybe that doesn't make as much sense in some scenarios.
I should’ve probably said I was thinking of a specific intereaction. I wanted to see if the bones oracle bonus against poison would help against both damage rolls. Rereading the spell, there are no saves to roll at all so it didn’t even matter.
It’s just funny to think about but if the explosion was meant to have the fire trait, multiple overlapping flammable fumes would explode in a chain reaction.

Actually, that sounds perfectly reasonable to me.
If you have multiple gas leaks in a hallway and each is creating a cloud of flammable gas in an overlapping area, then lighting one of them will cause combustion - which will then ignite the next area too. Not sure why it shouldn't work for magical flammable fumes set up in the same way.
