I have a 2001 F-450 7.3 PSD. I was pulling a trailer from CA to TN and had the same problem - injector cup leaking fuel into overflow. I had the cups and injector O-rings replaced, but then had the issue of having the radiator and a couple of cooling hoses start to leak. The shop told me that it was because the diesel had eaten away at the O-rings. I checked with Ford and two other shops and both confirmed that diesel can eat away at the O-rings and the gasket material between the tank and radiator (would only hold about 6 - 7 lbs pressure). Since the truck was over 100k miles and all original, I replaced the radiator, water pump and hoses as I did not want any future problems. When replacing the injuector cups they did not have to remove the heads either.
Good luck with yours.
