Bleeding the fuel system on a 3.2l

Just wondering if there is any trick in getting the air out of the rails and lines on a 3.2l. Sould it bleed itself or is there a fitting that should be loosened while under pressure?

Also what about bleeding the fuel filter?

I'm thinking I have some air trapped and have tried a few ways to bleed it off but still having problems.

What's your idea?

The only access I know of is the port used to test fuel pressure which is just a threaded cap with a ball bearing (?) inside on the back left (driver) side fuel rail. This thread is of interest to me since I've got my lines all disconnected for a engine drop and valve guide replacement and the fuel has drained out. I assumed it would fill up once I ran the pump/starter long enough after I get everything hooked up. Has this not worked for you?

I run the fuel pump from the fuse panel. I use a key and cross two fuses together from the top post.
You can hear air traveling back to the tank. I don't think it's necessary though. I've changed injectors and lines and pumps and never had a problem.
I guess to answer the question I believe it bleeds itself

Buck- I believe it's bleeding itself fine. Just curious if anyone has had trouble in the past.

Jerry- I've ran the fuel pump a couple of times by itself and hear air every once in a while. I'm now looking into a loose fitting or line that may be sucking air. I would think it would leak fuel from the pressure but just need to check for my own sanity.
