Here is a dumb suggestion, possibly is your fuel filer the original type, if so did it get put back in the right diection? There is a hole on one side and not the other. The hole goes towards the fuel line, just in case you didn't know. Just a thought.

Mine was doing the same thing. I adjusted the float level and I also discovered a vacuum leak. I am not sure which one corrected the problem so if I were you I would check for a vacuum leak first. My leak was in the lines for the heater/cooling vent control as I have AC and the vents are controled by vacuum
