priming the injectors

So tomorrow I plan on doing this. I have all my injectors out and thoroughtly cleaned.

I realize the fuel lines need to be pressurized. What I figure is to put all the injector in and connect all the hoses but do not hook up the power to them. I have the hose after the fourth injector lose so the fuel pump will pump out all the air out the end. Once I start getting gas flow, I tighten it up. That way I have gas going to all injectors. Then I hook the power lines to the injectors.

Am I doing this right or not? Do I have to worry about doing this at all?

Any advice would be appreciated....Thanks, Jason

Don't worry about it. If you want to be sure, turn the key from "off" to "on", wait 2 seconds, turn it off again. Repeat a couple of times, and the high-pressure loop of the fuel system should be full. It's not that much volume, and the pump puts out quite a bit even in the ~1.5 second priming pulse.

Air will get purged out the fuel pressure regulator and pushed back into the tank. No problem.
