fuel won't preview?

[simmsimaging]

I just thought I'd try using Fuel as a source for fluid rather than temperature to see if it reacted any differently (should it?) But for some reason I cannot get Fuel to show up in the preview or in the render. The values should be okay - they work for Temperature and for Smoke, but not when I do it with Fuel.

Is there a trick for previewing Fuel?

by default it's not exported, could this be the reason?

I turned it on in the rollout but it didn't help.
