tank's the lower tank has no problem.I,can get fuel
to the Racor
filter from the top tank and the engine
start's run's for 5 to 6 minutes shut's down.Let it sit for a minute of so the engine
restarts but will only run for 1or 2 minutes.
From what I am not hearing you did not replace the vent line to the top tank, therefore, it is possible that the vent line is plugged. I had problems because my vent line came down, it then had a low point which filled with liquid, this was a problem when filling the tank not when running, but if crud grew in there for a while, it could be a problem for both filling and running.
If I had the same problem and could not solve it quickly, I would put in one or two draft
gauges zero center with inches of water
range, 15 inches should work well, and Dwyer gauges are not real expensive. You would have to check material compatibility with diesel
There are different ways you could hook them up.
My preference would be to have one before the fuel filter
and one after, each with the other side of the gauge to atmosphere.
This would tell you most of what you would want to know, if they were below the fuel tank
they would even give you an indication of fuel level in the tank.
Good luck, you can still test the vent by just trying to run the engine and venting through the fuel fill cap.
