That means really good, right?
PVC is resistant to diesel

hoses as the lining to give the hose diesel resistance.
A short section of our diesel fuel
fill line is Schedule 80 PVC - it was done by the builder
as a way to manage some sharp bends in restricted space. The only thing I am careful of is that if I add an additive to the tank I flush the line with diesel immediately after in case the undiluted additive has some effect (unlikely I would have thought though).
Also, as I mentioned in another thread a while back, our exhaust
from the water lift muffler
to the transom discharge was fabricated by the builder
in Sched 80 PVC with no problems (I rerouted a section of it recently and so was able to inspect inside it and was like new). I actually got rubbished in that thread by some claiming PVC was not diesel resistant but the knowledgable calvalry soon arrived and proved it was by providing some links
For myself, I would not transpose its chemical resistance into a claim that it was structurally suitable for constructing fuel tanks
though, especially if flat paneled.
