I'd check your fuel pressure at the top, it's possible debris entered the fuel system and is restricting flow. It is also possible to have gotten a bad fuel pump, I've purchased a new fuel pump that did not work, it took me days to figure it out, but sometimes they don't work. If the pump is good but you have low fuel pressure replace the filter again and run compressed air backwards through the lines. Do this in as many small sections as possible, anywhere that you can open the fuel system to the next point, pay close attention to rubber to steel connections as the rubber hose is larger and the steel line makes a bottleneck.
