Post Fuel line is cheap.

I have see this before - just like the guys above said - fuel line can be cause. I have seen it many times. Even chunks of asphalteen can be stuck in there.

Also inside the tank at the just inside of the out flow pipe it can be plugged with scaling or debris.

The junction block can also be plugged.

I would replace the fuel line -- as in boat units ($) -- it is relatively cheap & not worth risking have the power stoppage of gen set due to this issue.

Blow back through the lines backward of the flow with a little compressed air to free any plugging that is loose.

Next ----------

Next Make sure the water level shut off check ball in the RACOR filter is on the correct side of the upper rubber seal - I have seen these get in the upper side & cause exactly what your experiencing.

To test - remove the check ball completely & refill & prime RACOR & then run it & see what happens with vacuum & fuel starvation.

That is a good one every one misses.

Good luck.
