Why would there be diesel in my radiator?

(1999 Ford F-250 Super Duty)
in Mineral Wells, TX on May 13, 2010
My truck had a small diesel leak and upon further inspection I took the radiator cap off and found that there was diesel in the radiator. Is there some water/diesel seperator that could be making this happen?

Sounds like one or more of the injector cups is leaking. They use a special Loctite that seals them to the heads. if they come loose or crack it introduces fuel from the fuel galley into the water jacket. The removal tool is a giant tap that cuts into the cup and then is slide hammered out and a new cup is driven in with the appropriate sealant
