Paul,

I think you might have found the problem. Absent a service manual, my best understanding is that fuel should be at the injector pump at all times. The bubble above the fuel level in the filter is not the problem but the electric fuel pump might be. That couple of seconds it takes fuel to reach the injector pump tells me that air is being pumped into the injector pump during that time. The service manual would also have a spec for the proper fuel pressure. I have no idea what that might be but if you have an automotive type electric pump they are usually set at 4-7 psi.

Another thought... is the fuel return line in place? Low side won't bleed without it.

I'm not a big fan of replacing mechanical pumps with electric ones on diesel engines. If it were me, I'd replace the OEM mechanical pump and using the service manual make sure all the lines were in place and then bleed both sides per the manual and then at least I'd have a know good starting point to work from should the problem continue.
