Did you replace the filter or clean it? Replaced
Also may pay to run injector cleaner through it as you may have dirt in the injectors if filter was bad. good idea
Also does it now run from the tank or have you not tried? Tried after i pressurize with the bulb, disconnect and reconnect main line. runs for about 15 seconds then dies.
Finally check fuel pressure at the rail to see if its high or low as your problem could be caused by the pressure regulator. Going to pick up a gauge tomorrow. where is the regulator?
