This engine is in an excavator, but used for everything. Machine fired for me in the cold, then started to stumble, surge die a couple times. I am confident it is a fueling issue. I removed the water separator (1st filter) and rusty crap dumped out of it.
There are two drain lines on the 2nd filter that I opened and neither of them produce a drop, so I unscrewed that filter a bit and there is certainly 'some' fuel hiding in there so I don't know what to think about the drain valves right now. The 2nd filter runs inverted so she is going to dump if it's loaded.
Beyond this, I am unsure about fuel system priming in this situation. The machine does have a lift pump that pulls fuel from the tank, and pushes it through the filters and to the HEUI pump. The book calls for "open the drain and use the manual pump to purge".....Yeah, it ain't got none of that! I can't find any procedure without the manual pump device.
