I pulled the fuel pump today but first I completely emptied the fuel tank with a hand operated vacuum pump. Bench testing of the pump confirms it to be dead.
There are lots of good articles on replacing the fuel pump, but one little detail seems to be missing - exactly how to disconnect the banjo bolt. It seems easy enough until you try to get a wrench on the back side nut. No ordinary wrench will fit, so you either have to grind one to fit or use needle nose vice grips inserted at an angle. I have included a photo I took once I had the pump on the bench to show how little clearance there is. I tried but was unable to remove the blue plastic shields. I also tried to use a wrench without grinding it and all I managed to do was to round the corners off the nut

so vice grips became the tool of necessity.
