Sometimes the fuel can back flow from the delivery hose and this would result in excessive air in the system and not allowing you to use the manual pump to pump the fuel back up. Remove the fule filler cap and apply low air pressure to force the fuel forward to the filter.

If you are not able to do it, remove the filter, fillit up with clean diesel and reinstall, Start the engine and let it self bleed. Try keeping the throttle open slitghlty or reving it to keep engine from stalling until it stabilises.
