New to me tractor hasn't been started in about 10 years. glow plugs seem to be working. Blead the fuel system seems like very little fuel is coming out of injection pump blead injector lines get smoke but no fire. No fuel is coming thru the injector return lines. hooked it up to 2 big batteries it turned over nice and fast. Anyone have a disassembled injection pump drawing? I don't want things flying across the shop should I open the pump.
