I refill the racor primaries from the top, so very little air stays in, cleaning up any I puah out when I put the top back on.
For the 2ndary, when installing the new filter, I remove the old, as well as the old top gasket (in the underside of the head), and the bottom gasket. I think there is also an o-ring. I replace all three, noting that the top gasket goes up in the head, not on the top of the filter or it will block the ports on the filter. Then, I place the new filter on top of the bottom bracket.
Now, here is my trick. It works for me, but others have cursed it. I gently squeeze the filter and bottom together and blue masking tape them together around the circumference a couple of times.
I then fill the filter with sea foam (just a convenient source of clean diesel substitute) and reinstall, holding the filter and bottom together as best as I can while I do. In doing so, I spill a tiny bit, so clean it up.
Normally, taking care to fill the racor and doing this with the filter, I don't need to bleed. It starts right up, runs rough for about 2-3 seconds, and I am good.
If you don't do it with your trick, then open the bleed screw on the pump, it is tiny hex nut on the face and bleed there until it is really bled. If you do that, you won't need to bleed at the injectors. If you rush it, you will. And, for the final bit of bleeding past the pump, you'll need to bump the starter a small few times to turn the pump, etc.
Good luck!
