If, after installing your new fuel filters, you reinstalled the check valve in the fuel line just ahead of the IP (and the check valve is functional) you should not have an issue with "Fuel Bleeding down". Assuming a good check valve, bleed air while cranking (throttle opened) by cracking the IP fuel-in fitting until clear. Then, while cranking with the throttle open, crack the fuel line at each injector one at a time until no bubbles.

Where is the check valve? I never installed one does it have one already? If so where I will make sure its working.[/QUOTE
Rob,
An evening on the puter with the TM I linked to, focused on the fuel system, would be of great help to you.
