Over the summer I stored aproximity 20 liters of kero in an old self made PVC water container. I got it out today to start up the old kero heater i noticed it had a funny smell to it and odd tint?
Could it have started to break down the PVC?
Without looking into it I dont know but probably yes, plastics for chemical storage are often fluorinated to protect them.
I'd guess the opposite, as PVC is pretty inert, like PE and PP etc. ???
Most likely it has developed bacteria growth or something.
UPVC chemical resistance is ok but some mild attack

If the joints are done with a general commercial grade (Crap) adhesive with low PVC content it could be something leaching out of that.
If you have any rubber seals this is a high probability of being the issue as at best the rubber used is generally neoprene or lower natural rubber both of which are going to give grief as NBR (Nitrile) or viton should be used.
