Yes if you should be able to bleed the air out at the secondary filter however the Racor should have it's own vent. One tip I picked up here and put on last year was to install an outboard type priming bulb just where the line comes out of the tank.
Then to purge air all you do is go to the first filter and open the vent, pump the bulb till you see solid diesel come out. Go to the secondary filter and repeat. On my 2GM I have never had to bleed off at the injector.
If you engine starts and runs fine for say 15 minutes or so then I would think you do not have air in the lines.
Another thought you could have an air leak, check all you connections.
