Hi there hope i can be of assistance.
Ok there are a few techniques on how to do this. The best and easiest way is with the use of a vacuum hand pump. You can get these from any motor factors, usually justy called hand primers.
First prime the filter with diesel. Connect the hand primer to the supply line for the filter. The with the igntion on work the hand primer to draw fuel up to the filter. Then quickly connect the pipe back on to the filter and start. Leave it ticking over for around 5 mins to allow any air out fo the system.
If you dont have a primer then you can try towing the car for around a mile with the ignition on and this will draw fuel back upto the filter.
Note: dont attempt to crack the injector pipes to try and bleed.
