When you get toward the bottom of a tank of diesel, take a sample of your fuel.
Disconnect the fuel line that goes to the high pressure pump and have the lift pump fill a tall narrow clear bottle.
Let it settle for a while and see what you have.
If your purge cycles have been short, there may be a lot of VO in your diesel tank. Blending in Florida should be just fine up to a point. I don't know what that point is, but if you have almost all VO in your diesel tank, that could be a problem. Then you may want to consider adjusting your purge system.

You might want to do this on your jeep too, just so you know what's going on with it.

I will start a separate thread on CDI purge cycles.
