Is the fuel filter housing empty prior to you priming it?
This new filter system you installed is it mounted in the same place or somewhere else on the vehicle?
Thanks, ***** ***** the one way valve in your filter is bad. When you shut the engine off the fuel supply line is pulling a vacuum on the supply line at half or below half tank and drawing fuel out of the line from the injector pump and filter housing.

The fuel filter housing has a valve to prevent fuel from gravity flowing back to the tank.
I am sorry but I'm seeing no progress in your and my communications. I am going to opt out and let you wait on the list for another to help.
Best of luck.
