Just a quick update on the Century fuel issue.
We have changed everything on the fuel system except the injector pumps, i.e. all fuel lines, fuel pump, fuel filter and sediment bulb. I cleaned the bleed off valve internal parts and finally trailered the tractor and left it a a diesel mechanic for about three weeks. He worked with it almost everynight and still couldn't find the problem. Now it works perfectly ! The only difference is the outside temp. It's now fairly cold. I'll be back with any updates.
thanks for all your suggestions.

Outside temps PLUS in your cleaning and other work you have drained the water separator, which could have been icing up when very cold.
You have also cleaned out a lot of other places that might have been causing the problem.
