Deisel Fuel in storage

[Monstertorque]

I think I have some parafin separation going on in about thirty gallons of stored deisel. It plugs up the removeable strainer in the top of my fuel tank when I pour the fuel through the strainer into my Mistsubishi tractor. Does anyone know of any way to reconstitute this fuel? In other words, what can I do to get the parafin to go back into suspension? The deisel has been stored for about 1 1/2 years in a sealed plastic drum. Any help would be appreciated.
