I've had very bad luck with glass/chrome fuel filters. They have small holes for fuel flow, and over half the attaching thread is cut away for more flow, making them weak. The center rod is made of brass so is none too strong to begin with. Mine snapped in half while idling in the driveway, saving me from another engine fire! I suggest pitching the filter & running direct to see if it makes any difference. If yes, get a large sized filter from Holley or other vendor. Stock 4bbl carbs nearly always have a sintered brass or paper fuel filter built into the inlets (2 on most carbs) that will work fine for a while, then plug up and again restrict flow.
