I just wanted to say that i have had a nasty fuel leak for awhile now. Bought the Fuel bowl o-ring rebuild kit from Dieselorings.com installed it today and i couldnt be happier. Almost every oring that i pulled off just fell apart. Very detaied instructions too. I'm pretty sure the fuel system hasnt been running on the pressures that it should have been because almost everything was leaking whether it was a big leak or slow drip. Anyway if your having the same problem go check them out. They have other stuff too not just o-rings.
