Tom, I've had great experience with Diesel Purge. I've used it twice to great success. When I bought the 92, I initially had a lot of stalling, white smoke smelling of raw diesel. I ran it off the purge and the motor runs fantastic, smooth, no nailing and no white smoke. My '98 also no longer nails, it was nailing at idle after being re-nozzled 40k miles ago. It was what I assume to be some carbon, but needless to say it's smooth as silk now.

I think it's best to remove the tank. There is a lot of sludge and algae plugging up the filters. It's all over the filler neck as well. If you stick your finger in you can pull out sludge. It sat for two years with water in the diesel and algae growing.
